Project Scorpio

[Tech Geek 69]

Now it seems the position of specs superiority has changed hands with the reveal of their successors. PlayStation 4K Neo currently has a mooted 4.2TF while Microsoft's Project Scorpio trumps it with around 6TF - a 43 per cent advantage. All of which is fascinating of course, but the question is, what is a teraflop and to what extent are these seemingly vast spec differentials actually indicative of performance and indeed the gameplay experience?

At a basic level, a 'flop' is a floating point operation - a basic unit of computational power. When applied to the AMD graphics technology at the heart of the Microsoft and Sony consoles, the calculation is really simple. You multiply the amount of shader cores in the GPU by its clock-speed. With AMD hardware, you'll find 64 shaders per compute unit. Xbox One has 12 CUs, PS4 has 18, giving us a total of 768 and 1152 shaders. The clock-speeds of the two consoles are 853MHz and 800MHz respectively.

   

• Scorpio Scenario #1: 3584 shaders x 840MHz x 2 instructions per clock = 6,021,120 megaflops/6.02TF
• Scorpio Scenario #2: 3840 shaders x 800MHz x 2 instructions per clock = 6,144,000 megaflops/6.13TF

speculation here assumes a lower clock speed for Scorpio, as its processor is likely to be significantly larger than PlayStation Neo's (larger processors generate more heat, generally seeing them run at lower clocks). And we are assuming that Microsoft is using the upcoming AMD Radeon Vega part, confirmed via a leak to be using 64 compute units or 4096 shaders, because hitting 6TF using the same Polaris technology as PlayStation Neo would require an extreme clock-speed on the processor.

• Scorpio Scenario #3: 2304 shaders x 1302MHz x 2 instructions per clock = 5,999,616 megaflops/6TF

Guys!

Peasant still gonna become "Scorpio Peasant" (WITH 6TF OF COPMUTE PERFORMANCE!!)

 Oh wow, it's faster than 480.. except nobody cares. It's a shitty console. "Real 4k" will be 4k30

And console optimized

4k 30 with dynamic scaling resolution tm that can change to 1800p if it drops below 20

 

console crap
