Forums - Microsoft Discussion - Teraflops are NOT a Measurement of Gaming Performance

There seems to be a misconception on how teraflops relate to gaming performance, this is partly due to Microsoft's emphasis on 6TF for their Xbox One X marketing, and now they're emphasising 12TF on the Xbox Series X. 

GPU's are far more complicated than that. In the context of supercomputers, then Tflops can be used to ranked the sheer calculation performance.

So a little breakdown of gaming GPU's and their Tflops can be found in this table:

GPU Tflops
RTX 2080ti 13.4
RTX 2080  10.1
RTX 2070 Super 9.062
Radeon VII 13.8
RX Vega 64 12.7
RX 590 7.1
R9 Fury X 8.6 
Xbox One X 6
PS4 Pro 4.2


1, If Measuring performance this way was comparable then, 2080ti would tightly match the Radeon 7


2, Vega 64 would be better than a 2080


3, R9 Fury X would be comparable to a 2070 super

How do these comparisons work out? (Using userbenchmark. due to different games and different DirectX under different platforms working different, using a single overall means of comparison would do.

1, 2080ti is 52% Faster despite having lower Tflops.

2, 2080 is 24% faster (https://www.youtube.com/watch?v=7kP0j_PzS-4&t=282s Even with a 2060, it handily outperforms the vega 64 with it's 'measily' 6.4 Tflops)

3, 2070 super is 67% faster

This is obviously not a surprise to anyone, but shows that there are much more that comes into gaming performance on a GPU, including TDP, Memory size, memory speed, core clock speed, core count etc etc etc. 


TL;DR

12TF tells us nothing about the performance capabilities of both the PS5 and Xbox Series X. If anything it's probably gonna be like a RX 5700 XT 'super' edition. As the base 5700 XT is 10 TFLOPs.

I disagree with you essentially blaming MS. This whole teraflop thing started with X1 and PS4 around 2013.

I believe Sony touted 4TF even before we heard about X1X's 6TF. It also made sense given all these specs were relatively the same, so the teraflop comparison had validity for 8th gen consoles.

I think MS has thrown out the teraflop figure for Series X for two reasons. First, to the average person that simply means significantly more GPU power and it certainly has that. Second, MS may be confident they have a more powerful machine for the next gen and want to boast.

But you can compare TF between same manufacturer

Instead of seeking to convince others, we can be open to changing our own minds, and seek out information that contradicts our own steadfast point of view. Maybe it’ll turn out that those who disagree with you actually have a solid grasp of the facts. There’s a slight possibility that, after all, you’re the one who’s wrong.

You can always compare TF within the same system architecture.

If we take these rumours about 12TF XSX and 9.2TF PS5, the former is obviously better (as they use essentially the same system architecture).

Actual tests tell us how to compare TF between different system architectures and different technologies.

Nope. MS announced 6 Tflops in July at E3 '16. It wasn't until September of that same year that Sony revealed the Pro's specs.

Ah, okay.

Either way TF was already being discussed in 2013, especially as we started seeing resolution disparities.

But it's relevant given the consoles with more TF have also had more power in practice. Consoles are essentially using the same tech.

If the press and Microsoft says its a gaming performance measurement, then its true. Like with facebook, if its on facebook, then its true! XD



                          

"We all make choices, but in the end, our choices make us" - Andrew Ryan, Bioshock.

Wrong, everything else being equal, graphic card with same architecture, one being 4TF and the other 12TF is a huge difference. Thats like comparing an xbox S to an xbox X, but a bigger difference because the power of the X was not pushed in any way, games were not design for it.

Next gen, if base PS5 is 9 TF then games will be design for it, and those games will struggle on 4TF, major cuts, and would have slight advantages on 12TF.

We are not comparing teraflops from graphics from different years, those consoles will launch the same year, most likely the same week.

Wrong, I follow console gaming news every day, without miss, and I haven't heard about teraflops being talked until they announced the power of the X.

But this generation, both the X and pro were under-utilised, because games were build for the base consoles, next gen if the games are build for the 9TF ps5, then 4tf will struggle a lot.

People might say 1080p, fair enough, but you can't even buy 1080p TVs anymore, most gamers have upgraded to 4k TVs or the next gen consoles will make a lot of people upgrade.

People who don't upgrade are the ones who won't jump to next gen so early as games will be too expensive.
