Astounding GeForce RTX 40 series performance hinted at as potential release timeframe for Nvidia's Lovelace-based cards is offered up
An intriguing tweet by Greymon55 about future products from Nvidia has included some details about the potential RTX 40 series. The first thing the poster mentions is a possible release timeframe for the series, which is apparently the fourth quarter of 2022 or the first quarter of 2023. The latter has been hinted at before, with Nvidia announcing that the Grace server chip will be launched in 2023. This data-center part is also based on a 5 nm manufacturing process.
What will be most interesting, and exciting, for gamers and Nvidia fans is the comment of “3090 double performance”. Of course it is a vague statement, which is not surprising for this early stage. However, that is still a promising gain over the current Ampere range and lends further weight to the alleged “RTX 4080/4090” specs that were making news headlines back in December 2020. In terms of FP32 at 1.8 GHz, the Ampere GA102 chip offers 38.7 TFLOPs while the Lovelace AD102 reportedly computes at 66.4 TFLOPs.
A reply from a well-known Nvidia tipster, kopite7kimi, has offered credibility to this claim for the future RTX 40 series. The response simply reads “easy”, thus implying that Nvidia might have even more than double the RTX 3090’s performance levels to squeeze out of the top-end GeForce RTX 40 series SKU. With a supposed 18,432 CUDA cores, compared to 10,752 for the GeForce RTX 3090, the top Lovelace-based card already holds a lot of performance promise.
| Lovelace AD102 | Ampere GA102 | |
|---|---|---|
| Process | Samsung 5 nm (?) | Samung 8 nm |
| Graphics Processing Clusters | 12 | 7 |
| Texture Processing Clusters | 72 | 42 |
| Streaming Multiprocessors | 144 | 84 |
| CUDA Cores | 18,432 | 10,752 |
| FP32 at 1.8 GHz | 66.4 TFLOPs | 38.7 TFLOPs |
| Memory Bus | 384-bit (?) | 384-bit |
| Memory Type | GDDR6X (?) | GDDR6X |

3090 double performance
That's what I heard recently. Not sure if it's true.
