Nvidia GeForce RTX 3080 graphics gives your gaming PC wings

New graphics playing cards deliver alternative. For higher gaming, sooner efficiency and costly {hardware} gross sales. However in addition they deliver challenges, with driver points, design challenges and sometimes provide shortages. 

As delivered by GeForce RTX 3080-based graphics playing cards, the newest model of the corporate’s GPU structure achieves playable body charges in video games which use fancy RTX-specific features like ray-tracing and world illumination. Its AI-based upscaling characteristic, DLSS, enables you to lastly play in 4K at (incessantly) better-than bare-minimum body charges with out seen degradation in high quality. The GPU additionally lifts efficiency over predecessors in video games that do not benefit from the whizzy options by about 20%-40% on common, which is de facto most video games. 

However the 30-series of GPUs Nvidia launched at the start of September, powered by the brand new  Ampere structure, has already run into issues. There’ve been reports of instability with some third-party 3080-based cards due to capacitor design, in addition to price gouging due to shortages. And Nvidia has already bumped the ship date of the RTX 3070 — more likely to be one of the vital in style playing cards with costs within the $499 vary — till the top of October, although that could be to keep away from the inventory issues of the 3080.

However you present me a GPU launch that hasn’t had related issues, and I am going to present you a GPU that is only a ho-hum rote refresh. That is the value of taking part in on the bleeding edge, and why I all the time advocate ready earlier than opening your pockets for brand new tech. 

Nonetheless, I have never waited. In reality, I have been spending the previous few weeks with two RTX 3080 cards — the Nvidia RTX 3080 Founders Version and an EVGA RTX 3080 XC3, each operating within the Origin PC Chronos gaming desktop — and did not run into any points. Sure, there was one blue display of demise with no identifiable trigger. However the reported 3080 issues appear to be linked to the GPU clock exceeding 2GHz, and neither of mine ever rose above it, hitting only a hair beneath.

In case you’re planning to purchase a system with one in all these new GPUs ASAP, you may in all probability should go together with an air-cooled model till the redesigned liquid-cooling methods nearly all gaming PC makers supply have ramped up. As a result of the brand new playing cards are bodily longer than the 20-series, they do not slot in a number of the tighter areas, together with the Maingear Turbo into which I used to be initially hoping to put in the Founders Version. (Maingear is swapping out the cooling system of my eval unit and putting in the cardboard, so keep tuned for that overview.)

To improve your system, you may not solely want to ensure the cardboard matches, however that your energy provide (PSU) can deal with it. It actually wants a minimal of a 750w PSU, however most not-maxed-out methods have 650 watts or smaller. In that case, you may both should swap in one other PSU or go for the much less grasping RTX 3070.

There’s greater than only a larger energy draw. Along with switching to a 12-pin energy connection, Nvidia made a notable change for its 30 collection from its 20-series fashions:  It now neatly vents sizzling air out the again of the case as a substitute of into it, which was an enormous 20-series grievance on the time. However your precise configuration issues, too. For instance, the followers within the EVGA card vent blow principally out the highest (in different phrases, towards the aspect of a case in a tower), so that you may wish to contemplate a case design that permits for airflow out the perimeters.

In contrast to the earlier era of Founders Version playing cards, which blew the new air into the case, the 3080 vents out the again.

How briskly does it fly?

Although technically the RTX 3080 replaces the RTX 2080 Tremendous within the $699 worth class, it feels extra like a observe as much as the 2080 Ti card due to its specs, that are in the identical ballpark. It vastly outperforms the 2080 Tremendous because it has a lot extra of all the things: reminiscence and reminiscence bandwidth and ray tracing, Tensor (AI) and CUDA (texture processing) cores. It additionally requires much more energy than the 2080 Tremendous and Ti — 320 watts vs. 250w — and much more than the flagship Titan RTX (280 watts).

Along with the velocity advantages conferred by the second-gen RT and third-gen Tensor cores, resembling new algorithms and instruction units that make them much more environment friendly and a change to an 8nm course of dimension from 12nm, the 3080 (and 3090) have one other efficiency perk you will not discover within the 3070 or another lower-end playing cards Nvidia launches — GDDR6X reminiscence. Micron’s GDDR6X incorporates new signaling technology that primarily doubles the information fee over GDDR6, the reminiscence utilized by the RTX 3070 and 20-series playing cards. If that is extra spec element than you are used to, my guide to the best PC GPUs can supply a bit background.

So, how does the brand new 3080 carry out? In my hands-on testing, it is quick sufficient to common 1440p/70fps on Extremely high quality/Extremely ray tracing with out DLSS within the notoriously piggy Metro Exodus and 96fps in Far Cry 5 on Excessive. On professional graphics functions it was extra combined — nonetheless quick, however not outstripping the 2080 Ti by a lot in some functions (as much as about 10% on varied SpecViewPerf 13 checks and 15% or so on Unigine’s Superposition rendering benchmark). Utilizing twin shows in Lightroom Basic can get laggy and glitchy, however the RTX 3080 labored as easily as I’ve ever seen.

Apparently, I noticed no important efficiency distinction between the EVGA and Nvidia playing cards. That is uncommon, as a result of usually Nvidia’s motive for the Founders Version is to offer a best-case-performance instance of a flagship card. The EVGA did are likely to run a bit hotter when maxed out, although, about 88C vs. 85C.  

As quick because the RTX 3080 is and as a lot as I appreciated each the Founders Version and the EVGA playing cards, I might nonetheless wait to see how the RTX 3070 stacks up earlier than plopping down $700 — and see what AMD has up its company sleeve later this month, when it launches its RX 6000 collection. Between the upcoming consoles and new graphics processor bulletins, these are fascinating instances to be a velocity freak.
