There is the possibility that one of the SKUs in the upcoming “Lovelace” GeForce RTX 40 series of graphics cards from Nvidia could eventually break the 100 TFLOPS barrier in regard to graphical compute performance (FP32). A noted leaker claims 90 TFLOPS is on the horizon for a board featuring the AD102 GPU.

Leaker Greymon55 has doubled down on an old claim of how capable the high-end AD102-powered RTX 40 series boards could be. A leak from the end of 2020 suggested cards with a Lovelace AD102 GPU (potentially RTX 4080, RTX 4080 Ti, RTX 4090, and RTX 4090 Ti) could churn out 66.4 TFLOPS in FP32 (single-precision floating-point format) at 1.8 GHz. A later claim, made by Greymon55, stated a board with an AD102 GPU could offer 85 to 92 TFLOPS, with clock rates from 2.3 GHz to 2.5 GHz. Now, the same leaker has posted a reminder of this astonishing graphical compute performance, saying “if Lovelace gets up to 2.5 GHz, you’ll get about 90t of FP32”.

Although TFLOPS (tera (trillion) floating operations per second) rate is far from the only way of measuring a GPU’s compute performance and general handling of graphics output, it has become more accessible as a form of quick comparison tool for the wider public, as seen in the recent competition between the PlayStation 5 (10.28 TFLOPS) and Xbox Series X (12.15 TFLOPS) current-gen consoles. Nvidia’s RTX 2080 Ti took the PC gaming world to 13.45 TFLOPS and then Ampere came along and basically tripled that amount with the RTX 3090 delivering 35.58 TFLOPS in FP32 (single-precision floating-point format) and the upcoming RTX 3090 Ti supposedly managing 40 shader TFLOPS.

If a possible RTX 4090 board was this almost mythical unit capable of up to 2.5 GHz (RTX 3090 Ti = core of 1,560 GHz, boost of 1,860 GHz) then the +90 TFLOPS rate would be over 2.5 times that of the RTX 3090. This doesn’t mean a potential RTX 4090 SKU would be 2.5 times faster or better than an RTX 3090 though, but it does mean that there should be more than significant generational gains. Additionally, an RTX 4090 Ti or new TITAN board based on Lovelace microarchitecture could break the 100 TFLOPS barrier, which is almost 10 times more than the PS5. Of course, there will be a hefty power requirement for all this compute performance, which will be confirmed when the RTX 40 series purportedly emerges in September 2022.
