Hey, we all know that Project Scorpio / Xbox One X has a 6 teraflop GPU (that's 6,000 glops) right?
But what about the original 2001 XBOX with its Nvidia GPU?
Lets have a look at Microsoft's GDC 2000 XBOX announcement and the specs Microsoft gave us, and then what the final retail XBOX actually had.
GDC 2000 slides:
141.1 GFlops for the XBOX GPU huh? Pretty damn good .. Yeah right, I don't believe you.gif !!
But now lets A.) take away the fudged Nvidia Flops (aka NvFlops) and B.) see what actual floating point performance was with the final clockspeed of the real GPU, from a good source...
What is Xbox One X / Scorpio Engine GPU again?...
6,000 GFlops (6TF).
And the 'real' figure for the OG XBOX GPU:
21.6 GFlops.
So Xbox One X GPU has
277.7 times the raw floating point performance of the original XBOX GPU.
Obviously we're not taking into account the vast differences in architectures between Nvidia's NV2A (XBOX GPU) which was a hybrid of NV20 (GeForce 3) and NV25 (GeForce 4 Ti) and AMD's Polaris architectures, which also spans more than a decade and a half in time. Just the raw, single precision fp32 performance.
Bonus Edit! It is pretty well-known and accepted that Xbox 360's ATI designed 'Xenos' GPU pushes 240 GFlops, which means Xbox One X GPU has exactly 25 times more raw floating point performance of the 360's GPU :)
Note: This is purely for fun!
