New ATi 4870 vs. Nvidia GTX 280

I know its early, but next month will see the launch of the next gen cards from both Nvidia and Ati. I admit I`m a Nvidia man, but those new ATi specs do look pretty mean, ATi has faster clocks and more SPs but Nvidia has double the memory bandwith and built in Physx. ATi has had faster clocks and Sps this gen as well and nvdia still outpreformed though.pknyo

How is 122Gbps vs 141Gbps double the bandwidth?
It should be an interesting generation...

ATI shader clocks are slower.

ATI shader clocks are the same as there core clocks thats whats limiting them

theres obviosuly a problem that limits them from upping them seperateky otherwise they would have done it by now and if they did there cards would fly ahead.

ATI and nvdidia both handle physics processing but why do we want are GPU's doing physics processing, we want them to concentrate on processing graphics not physics. and most people have powerful CPU's which are generally not put to good use in games they really need to concentrate with physics on CPU's and visuals with GPU's. why make things more complicated, although i did hear of some nvidia physics running better than the new 8 core from intel or something??? cant remeber exactly but if its true then WTF! lol

The info on the 4870 is that clock speeds are - 850MHz/1050Mhz/1940MHz core/shader/memory. So they seem to have achieved that now but it is still way slower that Nvidia shader clocks who are pushing their shader clocks way higher. Hopefully it won't matter too much on this card.

I find it distrurbing that "our" GPUs should handle physics, sure physics is "cool" but they(the GPUs) should be used for graphics; not calculating if that barrel or box will hit the Spy´s head in Team Fortress 3

:)

How much new gen are these? What's the difference between the 9-series and this one compared to the upgrade that was the 8xxx's to 9xxx's (and ATI's equivalent)?

Aint the 4xxx series clock speeds higher than nvidia ones??

thats what i was saying we have these powerful CPU's but there not really put to good use to be fair

really finally lol

i would expect that even though the shader clocks may be slower than nvidia the fact that the core clocks and amount of SP's are generally higher it should balance it all out

looks like the next cards from both of them will be very close in terms of performance

Hey guys, if im planning on buying a new laptop soon, so should i wait for these new cards to come out? I mean my laptop is only gonna be in the 1000-1500 range but are the new cards gonna be in cheap laptops like that too or are the manufacturers going to update their laptops into better but last gen graphics card or will there be no change at all?

of course laptops are gonna keep updating and becoming better but they will always be a step behind PC bcoz of the power, heat and space limits.

waiting another 6 months could up your laptop performance considerably it just depends what happens in those 6 months. im not sure if they are releasing these into laptop versiosn im sure som1else could tell you

well it wont have an effect tillt hey come out thats if there makign laptop versions they will also be more expensive soo......

a 8600 is pretty good going for a laptop

have they fixed the lack of texture units?

First of all, the CPU is not becoming a bottleneck anytime soon, an old core2duo @ 2,66ghz can perform just as well in almost any game then your brand new E8400, because it is no where near 100% or even 80% maximum load.

As for GPU running physics better then an 8 core intel CPU, that is entirely true. Physic processing require a SIMD processor (single instruction multiple data) like graphic processing does. You can do that by putting many many cores (or SP) on one card with a limited number of instruction and then perform massive parallel computation with a limited number of instructions because the result of your calculation does not impact your next one. Intel CPU use a MIMD (multiple instruction mutiple data) processor (with some SIMD elements though but not much) to do most of your day to day processing because MIMD processor are more apt to compute a random set of instruction then a SIMD processor.

That is why the cell processor in the PS3 is wonderful at physic calculation, because it has 8 SPE which are basicly SIMD processors to physic calculation and 1 big MIMD processor for other task. But it's one hell of a job to program for this beast.

Within the next few months, Nviida will be launching thier mobile 9 series, and ATI will be launching thier mobile 3000 series.

i got 2600 xt now im willing to spend 350 on gpu.

my choices is 2x 3870 iceq3 or a 9800 gtx on a maximus formula se
