Force3D Ushers Forth HD 4870 SKU Specifications

Force3D has, today, announced the specifications of its first SKU powered by AMD's HD 4870 GPU. A core speed of 750 MHz, paired together with 512 MB of GDDR5 memory running at a frequency of 3.6 GB/s are the order of the day, whilst technicalities such as the presence of 800 stream processors and a 256-bit memory interface prove commonality with AMD's HD 4850 offering. Using Extreme settings, Force3D's own 3DMark Vantage results claim that their HD 4870 iteration has a speed advantage of 58% over the HD 3870X2.

its not quad pumped GDDR5 does 4 clocks per cycle so GDDR5 @1000mhz is 1000x4.

So GDDR5 @ 3.6ghz is really running @ 900mhz x 4 if you look at GDDR5 reviews.

Its SDR to DDR confusion all over again

FiReStOrM315selene NV card is expensive because the waffle that it's made on is expensive and the die for the gtx200 is huge!so they cant fit as much on the waffle
It's wafer not waffle (unless you mean the food)

interesting review, to say the least.

I'm impressed a single 4870 is out running the 3870x2.

Even still, the performance difference at this point is still within a very respectable range of the 280 and GX2 - I think a couple of new driver releases from the red camp will be able to narrow that performance gap even more.

I'm even more impressed by how well the card fares once the eye candy is turned on. It seems like in every game bench, 8xAA and 16xAF has very little impact on it's performance . . . and benchmarking at those high resolutions with full eye candy seems to negate any performance lead the green camp has.

That, right there, after the AA hit the 3870s were taking, is a major feat that ATI is deserving of much praise for! :toast:



-edit-

and something further I just realized as well - the specs of the 4870 appear to be near identical to the 4850, except for the presence of GDDR5. If the 4870 is truly running that much faster over the 4850 at the same GPU clock speeds . . . it'll be interesting to see how well they'll perform once the top-tier brands start releasing their OCed models.

This has been discussed many times before.
512bit GDDR3 < 256bit GDDR5
