s it just cpu and gpu or other parts of the machine as well?


I have no idea. I didn't do the testing or write the article. The GPU and CPU will do almost all of the work. Things like upscaler chips and sound processing can add to its 'horsepower' but that doesn't equate to performance at all. Lets just say that the ps4 will on paper be as good as a mid-high tier gaming pc and leave it at that.

i'm curious about this too know...what is the tflops of i5-3570k? I googled and it said 112 gflops...but isn't 1.8 tflops like 180 gflops? How can a PS4 processor have more computing power? Do i have this wrong? Anyone with clear answer...


Uh, 1.8 tflops would be 1800 gflops, not 180.

Know your metric system, everybody.

^ To add to the above . . . 180 Gigaflops (180 billion Floating Operations Per Seconds) would be .18 Tflops . . . .

ok, but my question was more general like if i was to measure the whole "horsepower" of a computer in TFLOPs, is there any other part of the computer besides the CPU and GPU I would have to look at?

edit: You more or less answered the question I just posted...sorry.

Not really no. As I said, some of the sound processing chips and such are capable of producing 'flops' but the amount would be insignificant as a whole. Even a graphing calculator could be measured for its flop potential which would likely be measured in megaflops. There would be no real reason to worry about .000001 of a teraflop when the big contributors offer numbers in the teraflop range.

how is the ps4's processor more powerful? It says 1.8 teraflops for the ps4...


That is likely the power of the whole machine including the gpu. Mine for instance is at 2.6tflops. Its a pretty useless measurement on its own to be honest. There are so many different factors involved in performance.


Yes, raw performance numbers are always under absolutely ideal circumstances and don't account for OS overhead/poorly coded software, cache misses, heat etc. etc. etc.

It's a measurement of a GPU's relative power. However, it's not a very useful one, and is really only useful for comparing the relative power of GPUs within the same series (for example, a GTX 580 is more powerful than a PS4's GPU (tying the 7870), but only has 1.5 Tflops).

Computers are weird. It's weird to think that anything happens 1 TRILLION times per second. I can't even count to 30 in one second
