Nvidia RTX 3070 Ti: Combined Evaluations, Low VRAM a Lengthy-Time period Drawback – ExtremeTech

Nvidia’s newest Ampere GPU is out as we speak and we’ve rounded up critiques from a number of sources to cowl opinions on the cardboard. Up till as we speak, Ampere has been hailed as certainly one of Nvidia’s strongest architectures thus far, and the RTX 3070 has been the relative star of the present.

The RTX 3070 Ti differs from the RTX 3080 Ti in a number of vital respects.

GPU Comparison Chart

Regardless of the title, the RTX 3080 Ti is successfully a alternative for the RTX 3090, as long as you don’t want the extra VRAM. The RTX 3070 Ti replaces 8GB of GDDR6 with 8GB of GDDR6X and boosts reminiscence bandwidth by 1.36x. However this swap comes at the price of energy effectivity and it might restrict the GPU’s scaling in future ray tracing titles, particularly.

We’re rounding up protection from The Verge, Ars Technica, and our colleagues at PCMag. None of those publications are thrilled concerning the value/efficiency ratio being provided right here. The RTX 3070 Ti gives a 1.2x improve in value (theoretically) with roughly a 1.07x improve in efficiency. We’ve embedded a few of PCMag’s benchmarks beneath, however if you wish to see their full suite of assessments, together with artificial and multiplayer video games, hit the complete evaluation.

PCMag writes, “Certainly, the RTX 3070 Ti, and its seemingly unobtanium standing shortly after launch, makes a renewed case for the Radeon RX 6800, when yow will discover it, within the around-$600 value zone for 4K gaming.”

Ars believes the RTX 3070 Ti is a comparatively poor worth because of “how a lot an extra $100 nets you from an RTX 3080.” The Verge writes: “I can’t assist however really feel like 8GB will probably be difficult sooner or later through the lifetime of this card, so it’s a disgrace Nvidia solely bumped the reminiscence spec and never the scale.”

8GB of RAM Is a Critical Ray Tracing Bottleneck

Usually, I don’t give a lot of my very own opinion in these evaluation roundups. I desire to deal with the conclusions of the folks writing the tales. On this case, nonetheless, I need to counsel any consumers contemplating the RTX 3070 or RTX 3070 Ti take a really cautious take a look at how a lot VRAM limits the efficiency of this GPU.

Once I reviewed the 6700 XT earlier this 12 months, we discovered proof that an 8GB reminiscence buffer was inadequate to allow ray tracing at 4K for each the RTX 3080 and RTX 3070. The 12GB 6700 XT went from dropping badly to the RTX 3070 to outperforming it at excessive decision.

This proof crops up once more within the benchmarks some reviewers ran for the RTX 3070 Ti.

In Watch Canines Legion, the RTX 3070 Ti manages 7.3fps with out DLSS. The RTX 3070 is oddly sooner (presumably because of driver immaturity), but it surely tops out at 9.6fps. The RTX 3080, in distinction, hits 31.4fps even in native 4K mode.

The three.27x hole between RTX 3070 and RTX 3080 efficiency in native 4K is completely defined by the RTX 3070 working out of VRAM. This hole doesn’t exist at 4K in WDL with RT disabled. The excessive efficiency of the RTX 2060 Tremendous relative to the remainder of the GPUs is a puzzle. Enabling DLSS kicks efficiency upwards to 32.5fps, from 9.6fps (or to 33.8fps, from 7.3fps). That’s as a result of DLSS renders internally at a decrease decision earlier than upscaling, and the RTX 3070’s VRAM buffer can deal with the workload at this level.

Not all ray tracing video games observe this sample. Management reveals no proof of VRAM strain and Cyberpunk 2077’s RT mode with 4K is so troublesome, the RTX 3070 Ti with DLSS can’t hit 30fps. It’s attainable video games like Godfall and Watch Canines Legion are exceptions — but it surely doesn’t really feel that approach. DLSS is obtainable to take the sting out of issues, but it surely isn’t supported in each title and it doesn’t at all times work equally nicely, although issues have improved an awesome cope with DLSS 2.0.

It’s not clear if Nvidia opted to restrict the RTX 3070 to push consumers in the direction of paying a premium for GPUs that will probably be able to working ray-traced titles easily at prime decision, or due to GDDR6 shortages. We haven’t heard something a couple of VRAM scarcity since early this 12 months, however that doesn’t imply it isn’t an ongoing drawback.

The RTX 3070 Ti isn’t a very nice worth in contrast with different playing cards within the Ampere household. However the level is nearly meaningless, given the paucity of GPUs on retailer cabinets and the inflated costs they proceed to promote for. Beneath these circumstances, anybody who can decide up an RTX 3070 Ti at MSRP is a fortunate particular person certainly.
