NVIDIA GeForce RTX 40 Series Specifications Change Leaked Out
Some updates.
RTX 4090, AD102-300, 16384FP32, 384bit 21Gbps 24G GDDR6X,
RTX 4080, AD103-300, 10240FP32, 256bit (?18Gbps 16G GDDR6?),
RTX 4070, AD104-275, 7168FP32, 160bit 18Gbps GDDR6 10G.
And DO NOT expect a lower MSRP.— kopite7kimi (@kopite7kimi) June 23, 2022
Some new details on the NVIDIA GeForce RTX 40 Series graphics cards have surfaced online courtesy of Twitter user Kopite. It appears that the RTX 4090 will be getting 16,384 CUDA cores instead of the earlier reported 16,128 CUDAs, giving it an upgrade from 126 streaming multiprocessors to 128. Other specification details remain the same, 24GB GDDR6X with TDP expected to reach 450W.
As for the RTX 4080, it is expected to launch a month after the RTX 4090 and is known as the AD103-based card. It will having 10,240 CUDA cores and 16GB GDDR6 memory. The latter may be subjected to change as remaining with GDDR6 would make it slower than its predecessors, but it’s worth noting that it does have bigger L2 cache.
| Model | GeForce RTX 4090 | GeForce RTX 4080 | GeForce RTX 4070 | GeForce RTX 4060 |
|---|---|---|---|---|
| Architecture | Ada (TSMC N4) | Ada (TSMC N4) | Ada (TSMC N4) | Ada (TSMC N4) |
| GPU | AD102-300 | AD103-300 | AD104-400 -> AD104-275 | AD106 |
| Board Number | PG139-SKU330 | PG139-SKU360 | PG141-SKU341 | TBC |
| SMs | 126 -> 128 | 80 | 56 | TBC |
| CUDA Cores | 16128 -> 16384 | 10240 | 7168 | TBC |
| CUDA vs Predecessor | +56% (vs 3090) | +18% (vs 3080) | +21% (vs 3070) | TBC |
| Memory | 24 GB G6X | 16 GB G6 | 12 GB G6 -> 10GB G6 | TBC |
| Memory Bus | 384-bit | 256-bit | 192-bit -> 160-bit | TBC |
| Memory Speed | 21 Gbps | 18 Gbps | 18 Gbps | TBC |
| TDP | ~450W | ~420W | ~300W | 220W+ |
| Launch Date | September-October 2022 | October-November 2022 | November-December 2022 | January 2023 |
Lastly in the NVIDIA GeForce RTX 40 Series leak, the RTX 4070 is expected to go from 12GB to 10GB VRAM instead, which means a narrower memory bus from 192-bit to 160-bit. The CUDA core count is said to be 7,168, which means 512 disabled CUDA cores on the AD104 GPU.
For now, do take all the information with a grain of salt. The NVIDIA GeForce RTX 40 Series graphics cards are expected to launch somewhere between late Q3 2022 to early Q4 2022. We will report more on this as soon as information becomes available so stay tuned.
Pokdepinion: My PC suddenly has an itch for an upgrade. Granted, I’d probably wait it out first anyway.
