This is a strange comparison because the 3080 was essentially never (and still is not) available at the MSRP of 699 $ (719 €). Even now the cheapest 3080 I can find is almost 800 €, and that's with the new generation already out two years later. Before the crypto collapse you'd never see these under four digits.
However the overall trend is still correct - nVidia has kept the price for 1 TFLOPS very constant since 2016ish
2004: ~5000 $/TFLOPS for a 6800 Ultra (~0.1 TFLOPS, ~500 $)
2006: 1200 $/TFLOPS for a 8800 GTS (~0.4 TFLOPS, ~500 $)
2008: 500 $/TFLOPS for a 280 (1 TFLOPS, 500 $)
2010: 300 $/TFLOPS for a 580 (1.6 TFLOPS, 500 $)
2012: 160 $/TFLOPS for a 680 (3 TFLOPS, 500 $)
2014: 115 $/TFLOPS for a 980 Ti (5.6 TFLOPS, 649 $)
2016: 60 $/TFLOPS for a 1080 Ti (11.4 TFLOPS, 699 $)
2018: 51 $/TFLOPS for a 2080 Ti (23.5 TFLOPS, 1199 $)
2020: 48-76 $/TFLOPS for a 3080 (25 TLFOPS, 1200-1900 $) or around 50-60 $/TFLOP for a 3080 Ti (28 TFLOPS, ~1600 $)
2022: 40 $/TFLOPS for a 4080 (43 TFLOPS, seems to be in the 1600 $ region now)
- nvarsj 4y agoLooking at historic price per TFLOP makes no sense. No one has ever expected price to scale linearly with performance increase in subsequent generations. I know Nvidia wants that to be the case w/ the 4080 - but as can be seen, no one is buying that.
- adrian_b 4y agoEveryone has expected the price per Tflop to decrease at every generation. If the price per Tflop and the power consumption per Tflop do not decrease in a new generation of GPUs, then there is no reason for a new generation to exist. The power consumption per Tflop has continued to decrease reasonably well, but the price has almost stagnated, for FP32. On the other hand for FP64 computations, the price per Tflop has greatly increased during the recent years, due to the fact that both NVIDIA and AMD have restricted this feature to their "datacenter" GPUs, which have prices that are acceptable only for those who buy them in very large numbers and for whom the costs for the expensive GPUs are compensated by savings in rack space, power consumption and cooling. It seems that AMD has removed completely the FP64 execution units in RDNA 3, while NVIDIA provides only a 1:64 throughput ratio for FP64:FP32 in RTX 4000, so they should have better also removed completely the FP64 hardware, because a software implementation would be faster than that. Now a CPU like Ryzen 9 7950X has a lower price per FP64 Tflop than any GPU, which is opposite from a few years ago, when e.g. a Radeon VII had a much lower price per FP64 Tflop than any CPU.
- sliken 4y agoSure the trend is down. However Nvidia's is designing the cards to be cheaper and have less bandwidth, while charging a significant premium over the previous generation (1.7x or so). The cancelled lower end 4080 has less memory width then the previous gen low end 3060 Ti. So the RTX 4080 TFLOPs are higher, but require you to be more cache friendly then the previous gen.
- lostmsu 4y agoThis trend looks much better in tensor ops though.
