Nvidia GeForce RTX 4070 Review: The Common Island Has Arrived
Nvidia is positioning the brand new GeForce RTX 4070 as an important improve for GTX 1070 and RTX 2070 customers, however that does not disguise the truth that it is successfully linked to the last-gen RTX 3080 most often. The $599 MSRP additionally means it is changing the RTX 3070 Ti, with 50% extra VRAM and considerably improved effectivity. Is the RTX 4070 the most effective graphics playing cards? It is actually a better proposition than playing cards that value $1,000 or extra, however you may inevitably commerce efficiency for pennies saved.
The RTX 4070 borrows closely from the RTX 4070 Ti at its core. Each use AD104 GPU and each have 192-bit reminiscence interface with 12GB GDDR6X 12Gbps VRAM. The primary distinction aside from the $200 value minimize is that the RTX 4070 has 5,888 CUDA cores whereas the 4070 Ti has 7,680 cores. Clock speeds are additionally barely decrease in idea, however we’ll contact on that extra in our testing. In the end, we’re a 25% value minimize with a 23% discount in processor cores.
we coated Nvidia’s Ada Lovelace structure If you wish to be taught extra in regards to the options that drive the RTX 40 sequence GPUs, begin right here. The primary query right here is how the RTX 4070 stacks up in opposition to its costlier brethren, not to mention the previous-gen RTX 30 sequence. Listed below are the official specs of the reference card.

It is a fairly steep climb from the RTX 4080 to the 4070 Ti after which to the RTX 4070. Now we’re wanting on the identical variety of GPU shaders (5888) that Nvidia used within the earlier technology RTX 3070. In fact, there are numerous different modifications going down.
Chief amongst these is the huge enhance in GPU core clocks. Working at 2.5 GHz, the 5888 shaders will ship much more efficiency than the identical variety of shaders operating at 1.7 GHz — virtually 50% extra efficiency mathematically. Nvidia additionally likes to be conservative, and real-world gaming clocks are nearer to 2.7 GHz… although the RTX 3070 can be nearer to 1.9 GHz in our exams.
Its reminiscence bandwidth can be barely increased than the 3070, however its considerably bigger L2 cache will inevitably imply it performs a lot better than uncooked bandwidth. Switching to a 192-bit interface as a substitute of a 256-bit interface on the GA104 gives some fascinating compromises, however we’re pleased to have no less than 12GB of VRAM this spherical—the 3060 Ti, 3070, and 3070 Ti really feel a bit restricted lately with 8GB. However aside from utilizing reminiscence chips in “clamshell” mode (two chips per channel, on both sides of the circuit board), 12GB presently represents the utmost for a 192-bit interface.
Whereas AMD shadowed the dearth of VRAM on the RTX 4070 yesterday, it is essential to notice that AMD has but to announce its personal “mainstream” 7000 sequence components and can face related potential compromises. The 256-bit interface permits for 16GB of VRAM, but in addition will increase card and element prices. Possibly we’ll get a 16GB RX 7800 XT, however the RX 7700 XT will probably have 12GB of VRAM as effectively. That is actually true with regards to previous-generation AMD GPUs with extra VRAM, however capability is barely a part of the equation, so we have to see how the RTX 4070 stacks up earlier than declaring a winner.
One other notable merchandise is 200W TGP (Whole Graphics Energy) and Nvidia wished to spotlight what the RTX 4070 will use in lots of instances. little extra energy than TGP the place competing playing cards (and former technology choices) usually attain or surpass TGP. We are able to confirm that that is true right here, and we’ll go into the main points later.
The excellent news is we lastly have a next-gen graphics card beginning at $599. Naturally, there will likely be third-party overclocked playing cards that drive up the value with extras like RGB lighting and extra highly effective cooling, however Nvidia restricted this pre-launch evaluation to playing cards bought at MSRP. We even have a PNY mannequin, which we’ll study in additional element in a separate evaluation, however we’ll embrace the efficiency ends in our tables. (As quick as Spoiler: Founders Version.)
Above are the block diagrams for the RTX 4070 and the total AD104, and you’ll see all the additional stuff included however turned off on this low-end AD104 app. Not one of the blocks on this picture are going to “scale” and Nvidia hasn’t offered a die picture of the AD104, so we won’t attempt to decide how a lot house is allotted to the varied bits and items – not till another person does the soiled work anyway ( you, Fritzchens Fritz (opens in new tab)).
As beforehand mentioned, the AD104 options Nvidia’s 4th technology Tensor cores, third technology RT cores, new and improved NVENC/NVDEC items for video encoding and decoding (now with AV1 help), and a way more highly effective Optical Circulation Accelerator (OFA). contains. The latter is used for DLSS 3, and though Body Technology with Ampere OFA (or utilizing one other different) is “theoretically” attainable, solely RTX 40 sequence playing cards can present this function up to now.
In the meantime, Tensor cores now help FP8 sparingly. It isn’t clear how helpful that is on all workloads, however actually AI and deep studying have taken benefit of decrease precision quantity codecs to enhance efficiency with out considerably altering the standard of outcomes, no less than on some workloads. Consequently, it should depend upon the job being achieved and it may be obscure what works and sparsity versus FP8 versus FP16. Mainly, it is a drawback for software program builders, however ultimately we’ll see extra instruments (like Steady Diffusion or GPT Textual content Technology) that make the most of such options.
These concerned with AI analysis might discover different causes to decide on an RTX 4070 over its rival, and we’ll have a look at efficiency in a few of these duties in addition to gaming {and professional} workloads. However earlier than the benchmarks, let’s take a better have a look at the RTX 4070 Founders Version.
