Agent47 Posted October 5, 2020 Posted October 5, 2020 Coming hot off the heels of a potential RTX 3070 mobile GPU, a new post from twitter user @Avery78 (via Videocardz) shows a picture of Nvidia's desktop GA104-300 Ampere GPUs being validated for production. The picture originated from a user on the Baidu forums, but it has since been removed. As with all leaked info, though, we have to approach this with some caution, but it does appear to be legitimate. The GA104-300 is assumed to be a cut-down version of the GA104 die, with 5888 CUDA cores, 184 TMUs, and 96 ROPS. This would be the RTX 3070 GPU, which features the same specifications. However, it could also be a different configuration for RTX 3060 or RTX 3060 Ti. Two or possibly all three (3060 Ti) of those GPUs are expected to launch in the next two months, to compete with future RDNA2 products. The actual maximum core counts for GA104 is 48 SMs, according to the Nvidia GA10x whitepaper. (Page 40 says GA104 Full GPU with 48 SMs.) If there's going to be a faster RTX 3070 Ti, Nvidia would almost certainly need to move to GA102, perhaps with fewer GPCs and SMs enabled compared to RTX 3080. But the full or nearly-full configuration for Nvidia GPUs is normally labeled xxx-400 (i.e., RTX 2080 was TU104-400-A1), while trimmed configurations are xxx-300 (RTX 2080 Ti was TU102-300-K1-A1, while Titan RTX was TU102-400-A1). The pictured image could thus be something other than RTX 3070. Regardless, having RTX 3070 in full production comes as no surprise, as the RTX 3070 launches on October 29th. RTX 3060 and/or RTX 3060 Ti are likewise rumored to arrive by Black Friday, though Nvidia hasn't officially announced either part. Performance for the RTX 3070 should be somewhere around the RTX 2080 Ti as indicated by Nvidia's latest slide showcasing RTX 3070 performance vs the Turing generation. Let's hope the delayed launch will allow supply to surpass demand at least for a little while. Some images of a purported Nvidia RTX 3000 series GPU validation line have been shared online. Originally the images were available on the Chinese Baidu social media platform but were taken down quite quickly. However, thanks to Avery on Twitter and VideoCardz we can still ponder over these images and the various details revealed. Above you can see a tray of GA104-300 GPUs waiting to pass through their validation phase. Passing through the tests the result will be 'excellent', 'qualified' or 'unqualified', with the latter samples being re-tested before being judged to have failed to make the grade. The 'GA104-300' is a GA104 GPU being validated to the 300 spec which will be used for GeForce RTX 3070 graphics cards. VideoCardz reports that the "GA104-300 GPU is a cut-down variant of the GA104-400." According to the factory validation images source, the testing line pictured is used to validate approximately a thousand GPUs per day. We already have official confirmation that the GeForce RTX 3070 features 5,888 CUDA cores, a boost clock of 1.73GHz, and 8GB of GDDR6 VRAM. Last week Nvidia announced that the RTX 3070 was delayed by a fortnight, in order to have a better stock situation at launch. On the news blog post Nvidia shared an illuminating performance chart comparing the new RTX 3070 directly against the previous gen RTX 2070 and RTX 2080 Ti. Nvidia will launch the Nvidia GeForce RTX 3070 on Thursday 29th October.
