In the face of the "falling and falling" of graphics cards, NVIDIA may advance the release of ADA Lovelace to mid July, that is, geforce RTX 40 series** Recently, there has been an endless stream of revelations about ADA Lovelace's new products, and the specification information has become more and more detailed. The well-known informant @ kopite7kimi released the latest specification of RTX 40 series GPU again. It can be seen from the information disclosed that geforce RTX 4090 will adopt the same ad102 core as RTX 4090 Ti, but the specification shrinkage is inevitable.
In terms of specific specifications, geforce RTX 4090 core will have 16128 CUDA cores built in, an increase of more than 50% compared with RTX 3090, but 14% less than RTX 4090 ti**
In fact, the full blood version of the ad102 GPU has 144 sets of stream processor units and 18432 CUDA cores. However, NVIDIA should not directly release the full blood version of ad102, so there is another possibility of @ kopite7kimi's disclosure.
That is, 16128 CUDA cores will be released with RTX 4090, and then adjust the product strategy according to AMD's actions, so that "super" can return again.
While strengthening the core on a large scale, NVIDIA further increased the L2 cache of ADA Lovelace. Ad102 may be equipped with 96MB L2 cache, which is 16 times that of ga102's 6MB L2 cache.
In contrast, amd has greatly improved the chip performance by adding infinity cache technology to rdna2 graphics card and Ruilong 5800x** NVIDIA also hopes to bring greater cache capacity through 3D packaging technology to improve the core performance of GPU.
In terms of video memory, at present, the price of hbm2e and hbm3 video memory is extremely high, and it does not help the game performance. Gddr6x is the best choice for geforce RTX 4090. NVIDIA should equip the RTX 4090 with 24GB video memory with a speed of 21gbps. The bit width is still 384bit, and the total bandwidth is about 1TB / s.
ADA Lovelace's power consumption must be very "touching". Although the thermal design power consumption (TDP) of RTX 4090 is not as exaggerated as 600W, 450W will also make many power supply and cooling systems unbearable.
Judging from the RTX 3090 Ti already on the market, the power consumption of about 500W can also be suppressed by air cooling, but once the power consumption exceeds 600W, mixed heat dissipation seems essential.
What's more, gddr6x itself is a large heat generator, which may cause serious heat accumulation in the graphics card under multiple influences. The design of mixed water cooling + air cooling will become an inevitable choice for AIC manufacturers.
If NVIDIA releases geforce RTX 40 Series graphics cards in July, the pressure will also shift to AMD. Although amd also launched new products of radeon Rx 6x50 series not long ago, the overall specification and performance have not improved much, and its attraction to gamers is relatively limited.
As for when the GPU of rdna3 architecture will come, it is still a mystery. At least there is not much news at this stage. However, with the release of NVIDIA's new products, it is believed that AMD will launch corresponding products as soon as the end of the year.
