Nvidia GeForce RTX 3080 offers

The Nvidia GeForce RTX 3080 lastly follows up on the controversial Nvidia Turing lineup, bringing with it a lot improved efficiency however with out elevating the value. 

You see, when the RTX 2080 and RTX 2080 Ti launched, Nvidia courted a bunch of controversy by introducing these playing cards at increased worth factors – up from $699 (£649, about AU$950) to $1,199 (£1,099, AU$1,899) within the case of the GTX 1080 Ti to the RTX 2080 Ti). This led many to assume that the identical would occur this time round. 

As an alternative, what we get with the Nvidia GeForce RTX 3080 is a large 50-80% enhance in efficiency over the RTX 2080 on the identical worth level, to not point out a 20-30% enhance over the RTX 2080 Ti, which retailed for practically double the value. 

And whereas we’d have preferred to see the costs go right down to the place the Pascal 10-series equivalents would have sat, we will now verify that this actually is the most important generational leap in PC graphics we have seen in years – maybe ever.

Worth and availability

The Nvidia GeForce RTX 3080 is offered beginning September 17, beginning at $699 (£649, about AU$950) for the Founders Version. Nonetheless, as with all main graphics card launch, there shall be dozens of aftermarket graphics playing cards from firms like MSI, Asus, Zotac and extra.

Simply remember that a few of these aftermarket card designs might even see steep worth will increase over this Founders Version, primarily based on issues like unique cooling options and factory-tuned overclocks. However each RTX 3080 ought to kind of be within the ballpark of efficiency because the one Nvidia itself launches.

Options and chipset

The Nvidia GeForce RTX 3080 relies on the brand new Nvidia Ampere graphics structure, which brings big enhancements to each uncooked efficiency and energy effectivity. The truth that Nvidia has elevated the facility finances a lot over the RTX 2080 whereas boosting energy effectivity implies that the general efficiency profile is way above what any Nvidia Turing graphics card was able to. 

There have been apparent enhancements to the RT and Tensor cores – we’re on the second and third technology, respectively – however maybe the most important enchancment has been to the rasterization engine. 

By way of some intelligent optimization, Nvidia was in a position to double the quantity of CUDA cores current on every Streaming Multiprocessor (SM) by making each knowledge paths on every SM in a position to deal with Floating Level 32 (FP32) workloads – an enormous enchancment over Turing, the place one knowledge path was devoted fully to integer workloads. This successfully doubles uncooked FP32 throughput core for core, although this may not immediately translate into double the frame-rate in your favourite PC video games – a minimum of, not for a lot of of them.

What this implies is that, whereas the Nvidia GeForce RTX 3080 solely has 46% extra SMs than the RTX 2080 at 68, it greater than doubles the CUDA core rely, from 2,944 to eight,704. This interprets to almost 3 times the theoretical FP32 throughput from round 10 TFLOPs to 29.7 TFLOPs – a completely large generational leap. 

Whenever you pair the uplift in CUDA cores, with large boosts to Cache, Texture Models and Reminiscence Bandwidth – because of the transfer to sooner GDDR6X reminiscence on a 320-bit bus – gaming efficiency will get one of many largest generational jumps in years, even when it does fall a bit wanting that ‘2x efficiency’ goal that we’re positive some people have been hoping for. However extra on that later. 

Nvidia RT cores are additionally again – that is why Nvidia has the RTX title, in spite of everything – and so they additionally see large enhancements. Nvidia Ampere graphics playing cards, together with the RTX 3080, embrace second-generation RT cores, which can perform equally to the primary technology RT cores, however shall be twice as environment friendly.

When ray tracing, the SM will forged a lightweight ray in a scene that is being rendered, and the RT core will take over from there, the place it would do all of the calculations mandatory to search out out the place that gentle ray bounces, and can report that info again to the SM. Which means the SM is left alone to render the remainder of the scene. However, we’re nonetheless not at a degree the place turning on ray tracing does not have any affect on efficiency. Perhaps some day. 

Tensor cores are additionally twice as highly effective this time round, which has led Nvidia to solely embrace Four in every SM slightly than the Eight you’d discover in a Turing SM. Coupled with the truth that there are actually extra SMs typically, DLSS efficiency additionally will get a large enhance.

This technology of graphics playing cards is not all about gaming, nonetheless, and Nvidia has introduced a few new options to the desk that can make life higher for just about everybody with an RTX card.  

As an illustration, we have been already huge followers of RTX Voice, and Nvidia has lastly introduced it out of beta and labored it right into a fully-featured broadcasting app. Whereas RTX Voice filtered background noise out of your microphone, you may arrange Broadcaster to filter backgrounds out of your webcam – and even simply apply a blur. 

The video part remains to be in beta, and we did see some glitches, nevertheless it’s method higher than some other answer on the market for blocking out your background and not using a inexperienced display. 

One of many options we’re most excited to see applied, nonetheless, is Nvidia RTX I/O, which is an API that can work in tandem with Microsoft’s DirectStorage API, to route knowledge straight out of your SSD to your graphics card. In next-generation video games, this could not solely massively scale back loading occasions, but in addition mirror the groundbreaking I/O efficiency that has been teased with next-generation consoles just like the PS5 and Xbox Sequence X. Way over excessive body charges or fairly graphics, this expertise is critically necessary to future gaming tech. 

Sadly, it is a expertise that must be applied by recreation builders of their video games, and we weren’t truly in a position to see what sort of real-world distinction it would make. Although it’s one thing we shall be actively testing as soon as the expertise is broadly applied – and since the consoles are going to be utilizing related tech, we anticipate it would have a sooner turnaround than ray tracing did. 

So far as the precise Founders Version graphics card, Nvidia went with an all-new cooler design, which is far more sensible than something it is ever accomplished with a reference design earlier than. The corporate used a shorter, multi-layered PCB so as to have the again finish of the cardboard simply be all heatsink. By doing this, Nvidia was in a position to mount a fan on the again of the graphics card that can suck cool air by means of the heatsink, and expel it up and out of the case.

We have been a bit nervous once we first noticed this fan design that it could have an effect on CPU and RAM temperatures, because it’s blowing scorching air immediately over these parts, however even in our private rig, the place we’ve got a Noctua NH-12UA air cooler on an AMD Ryzen 9 3900X, we did not observe any distinction in efficiency. We guess it helps that almost all PC video games do not actually stress each the GPU and CPU to the identical excessive – not but a minimum of. 

So far as energy supply, that new 12-pin energy connector is certainly there, and we’ve got some combined emotions about it. It is clear that the brand new PCB design of the Founders Version card wants this smaller connector to make this new cooler work, we simply want that the two x 8-pin PCIe to 1 x 12-pin dongle Nvidia consists of was a bit longer. Because it stands, it is sort of laborious to tie it out of the way in which to not be instantly seen, however a minimum of aftermarket playing cards will not be utilizing it immediately. It is price noting, although, that Nvidia is making the 12-pin energy connector design out there to any producer – even AMD – that desires to make use of it. 

The Founders Version additionally simply has three DisplayPort and one HDMI 2.1 output for shows, which is sweet. Nonetheless, we do not like that Nvidia removed the USB-C output right here, as creators will certainly nonetheless wish to use this extremely highly effective card, and lots of pro-grade screens on the market are, in actual fact, USB-C screens. 

Regardless of our little points with the Founders Version – and regardless of pondering it was ugly when it was first proven off – it is a horny piece of {hardware} in individual. All black with silver accents, the RTX 3080 seems to be like a professional-grade piece of {hardware}. The one lighting is the ‘GeForce RTX’ brand on the facet of the graphics card in white, which can absolutely please any anti-RGB customers on the market. Plus, avid gamers that actually wish to go all-out with rainbow lighting may have that choice with third-party playing cards.

Efficiency

Take a look at system specs

That is the system we used to check the Nvidia GeForce RTX 3080 Founders Version:

CPU: AMD Ryzen 9 3950X (16-core, as much as 4.7GHz)
CPU Cooler: Cooler Grasp Masterliquid 360P Silver Version
RAM: 64GB Corsair Dominator Platinum @ 3,600MHz
Motherboard: X570 Aorus Grasp
SSD: ADATA XPG SX8200 Professional @ 1TB
Energy Provide: Phanteks RevoltX 1200
Case: Praxis Wetbench

Simply from Nvidia’s personal (overblown) advertising and marketing, we have been already anticipating the RTX 3080 to be a quick graphics card, however calling it “quick” is a little bit of an understatement. From the second we opened the field, it has been in our private machine, operating every thing from Ultimate Fantasy XIV to Management, solely popping out of our private rig to be plugged into our check bench for precise benchmarking. 

Earlier than the 3080, we had an Nvidia GeForce RTX 2080 Ti in that machine, and the distinction was instantly obvious earlier than we even begin measuring efficiency in a quantifiable method. As an illustration, one of many video games we play essentially the most is Ultimate Fantasy XIV – it is an issue – and in that recreation, notably within the newest growth, there have been moments the place the RTX 2080 Ti would drop beneath 60 fps at 4K. That does not occur with the RTX 3080. Actually, the sport is often operating anyplace from 75-100 fps at 4K with Most graphics settings, the place the RTX 2080 Ti sometimes chilled across the 60 fps mark – a large bounce in efficiency at round half the value. 

This story simply saved repeating itself time and again it doesn’t matter what recreation we performed. Metro Exodus maxed out with Ray Tracing and DLSS? Easy locked 60 fps at 4K. Management with the myriad ray tracing results? Silky clean. Even Ultimate Fantasy XV with all of the bizarre non-obligatory graphics results sits fairly at a gentle 60 fps at 4K. Accessible 4K60 gameplay is right here – even when we are utilizing the time period “accessible” very loosely right here.

Whereas the thermals in our benchmarks aren’t too thrilling, you need to remember that these have been recorded on an open-air check bench. In our closed tower, with two 240mm followers serving as consumption, temperatures peaked round 60°C – method cooler than the mid-80°C temperatures we’d sometimes see with the RTX 2080 Ti Founders Version. 

When wanting on the precise benchmark outcomes, it is clear that the Nvidia GeForce RTX 3080 is in a category of its personal, standing head and shoulders above even the RTX 2080 Ti. Proper off the bat in 3DMark Time Spy Excessive, the RTX 3080 is a whopping 63% sooner than the RTX 2080 and 26% sooner than the 2080 Ti – a large generational leap when you think about that the RTX 2080 was solely 40% sooner than the GTX 1080 once we reviewed it again in 2018. 

However Time Spy Excessive is not even even the best-case state of affairs for the RTX 3080’s beneficial properties. In Pink Lifeless Redemption 2, the place we mainly maxed out each single choice that wasn’t MSAA – multi-sample anti aliasing could be very costly and never price it – we noticed a large 87% enchancment gen-on-gen.

This falls wanting that 2x efficiency leap that was teased on the RTX 3080 reveal, nevertheless it’s positively nearer than we thought it could truly get. The RTX 3080, all advised, is between 50-80% sooner than the RTX 2080, whereas solely falling beneath that in Hearth Strike Extremely, the place it solely managed a 29% lead – however that is nonetheless a meaty benefit. 

That large hole in efficiency is just actually current at 4K, nonetheless, when the graphics card is freed from bottlenecks. There are lots of titles in our testing suite the place even the AMD Ryzen 9 3950X, paired with 64GB of RAM at 3,600MHz, held again the RTX 3080. That is why, as an example, the RTX 2080 Ti and the RTX 3080 are just about an identical at 1080p in Metro Exodus, however opens as much as a 19% efficiency benefit at 4K. 

Because of this, we actually do not advocate anybody truly purchase the Nvidia GeForce RTX 3080 except they are going to be taking part in at 4K, or probably 3,400 x 1,440 Ultrawide. The beneficial properties are simply not going to be there at decrease resolutions, so that you’re higher off simply ready for the Nvidia GeForce RTX 3070. 

The efficiency on provide with the Nvidia GeForce RTX 3080 even additional widens the hole that exists between Nvidia and AMD on the excessive finish, greater than doubling the efficiency of AMD’s strongest client graphics card, the Radeon RX 5700 XT in lots of exams. AMD Massive Navi goes to have an enormous battle on its palms if it needs to attempt to declare the 4K crown that the RTX 3080 simply received.

Purchase it if…

You need the perfect 4K efficiency
4K gaming is extremely tough to run, however the RTX 3080 is the perfect graphics card but for dealing with it. You’ll max out each recreation below the solar at this decision at or very close to 60 fps. 

You need next-gen prepared efficiency
With the subsequent technology of video games on the horizon, efficiency necessities are about to skyrocket. The RTX 3080 is considerably extra highly effective (a minimum of on paper) than the GPUs in both the PS5 or Xbox Sequence X. 

You might have an older graphics card
As a result of the generational beneficial properties between Nvidia Pascal and Nvidia Turing graphics playing cards have been fairly minor, many people held on to their 10-series playing cards. In case you have one in all these older playing cards, nonetheless, you may get completely large beneficial properties with the RTX 3080.

(Picture credit score: Future)

Do not buy it if…

You play video games at a decrease decision
The Nvidia GeForce RTX 3080 is a 4K graphics card, and as such, you actually should not choose this graphics card up for gaming at a decrease decision, you may run into bottlenecks with even essentially the most highly effective CPUs available on the market. 

You are on a finances
When Nvidia Turing launched, the RTX 2080 noticed a big worth enhance over the GTX 1080. And, whereas Nvidia did not increase the value, it did not decrease the value again to pre-Turing ranges. If you wish to get your palms on the RTX 3080, you are going to be paying a excessive worth – even whether it is price it.
