Is 1.2 teraops alot?

[postaldudeleo]

Stupid question coming from me. Heard of Teraflops but not teraops.

Is 1.2 Teraops vpu power out of a video card is alot?

What about 67 gflops of 36-bit persicion floating point power?

What about 200 gflops vpu power out of a video card?

Forgive me if my explanation is not very good, but to put it quite simply, flops are not a good estimation of speed. For instance, a Pentium 4, going by flops alone, would be more than twice as fast as an Athlon64.

Teraops... flop = floating point operations per second, I think, ops = any operation?

[postaldudeleo]

So is 1.6 alot? That would mean that this video card alone beats a ps3 and cost about the same! :cool:

[Yuriman]

What video card? Rating by teraflops is worse than rating a cpu by it's mhz. I'd say a 7800gtx is on par or beats PS3(likely beats), while XBox360's gpu is still a bit ahead.

And can you browse the forums from a ps3? :p

i havn't really been brushing up on my gaming consol knowledge but, your sayiing these new gaming machines like xbox360 and ps3 are going to have graphics that are as powerful or more powerful than the geforce 7800 series?

what are they going to have as far as cpu and memory?

[consumer9000]

A FLOP is a "floating point operation/second". Remember when the Apple G4 "Velocity Engine" touted being superior by breaking the gigaflop barrier? Well, now we're into Terraflop land, granted the software is coded to take advantage of whatever tricks enable such high processing performance.

Xbox360 will be on a form of the IBM PowerPC (G5) but with three cores. GPU is Nvidias 7800GTX derived RSX (its not much diferent)
PS3 will have IBM Cell processor (7 mini cores) and ATI's r500 (FUDO derivative)

mem I think is 256mb for the Xbox and 512mb for Ps3..not sure tho.

[Yuriman]

XBox360 has 3 general purpose cores running at 3.2ghz, and each one is capable of running 2 threads on a hardware level. PS3 I think also runs at 3.2ghz. It has 1 general purpose core, and 7 mini cores (correct me if I'm wrong). Most developers dislike cell, because in most cases the mini-cores are too specialized to be of any use. While cell can do a zillion teraflops in theory, in practice most games will likely not use anything but the single multipurpose core most of the time.

XBox360 developers aren't really happy either, though. Even though Cell and 360's cpu are at 3.2ghz, they are supposedly only do about twice the work of the 733mhz celeron in the original xbox, per core. They say they would MUCH rather have had 2 more powerful cores, or a single really powerful one. As it stands, these cpus are what make the consoles cheap, and are nowhere near an Athlon64 or Pentium 4 in performance.

Oh yes, and PS3 = 512mb of shared system memory, XBox360 = 256mb of system ram@ 700mhz, and 256mb of vram@ 700mhz. It also has 10mb of "cache" on the gpu.

EDIT: Anyway, the moral of the story is, you can't compare apples to oranges, and we will know soon enough which one is more powerful.

[postaldudeleo]

The ps3 has 1.2 teraflops. The VP990 has 1.6 Tera ops (but damn old drivers). What is in raw power, more powerful?.

The ps3 RSX is a 7800 card without the memory but an overclocked core by 90mhz with heatpipe cooling.

[deathman20]

As said before you can't compare RAW POWER unless its in a test. Only way to run something on a similar track is to have a 3rd party program to run on both systems to test out and give scores of what both are capibile of.

As he have found out in the past Mhz don't mean anything if it has nothing to back it up.

And keep this in mind. Microsoft is going to use the XNA game development technology, but PS3 developers (as ar as we know) will have to develop on their own.
