Most powerful graphics processor in the world

As far as I know the 4890 is not supposed to be the most powerfull. It is just to fill the gap between the 4870 and the 4870x2.

they are claiming it is the most powerful 'single'. 4870x2 is a double..
a friend of mine just got the 4890 for around R3500...

Not sure what reviews you have been checking but the guru one posted here, it loses to the 260 so in theory the 280-285 will thump it.
AMD made the same mistake when they were ahead of intel at one point, instead of developing they just charged more and did not develop and fell far behind, scotty you are right they should be looking to bring home the advantage.

ok, 1stly, I wouldn't put the Nvidia GTx280 and the HD4890 in the same boat... they aimed at different markets, and the prices are quite different.

However, the HD4870 competed with the GTX260, but didn't beat it, and i think this is why the HD4890 was conceived... It doesn't thrash the GTX260, but it does "win" (if you want to say a win is having 5 more fps while the game is running at 60+ fps)., look here here and here

And I think it's clear that the HD4890 wins here :)
 
Ok but explain how this article claims the 4890 the fastest processor in the world when it cannot even come close to the 280 or 285? what point is having good looking processor on paper but in action its a slow ass and then claiming it is the fastest?

Sensationalism is very poor i feel.
 
If i am not mistaken he is referring to the terraflops of computing power generated by the single gpu 4890, i do not think he was referring to games.

Shock note, there is more to life than gaming frame rates.

p.s. have not checked the flops of the nvidia cards (single gpu ones) so i can stand corrected :)
 
Well when ati claim they have the fastest processor considering they are making gpu's for gaming and the card is aimed at gamers i would have thought they meant games.

Does it make sense when a gpu maker claims they have the fastest gpu 99% of people will think it is the fastest gaming solution?

Not mention the heading is the most powerful graphics processor, so what else would it mean by fastest GRAPHICS processor? :p

hmmm... thing is that this is still using the same old gpu from the 4800 series, only with a few tweaks to make it a little faster... Honestly, I was expecting a lot more from ATI, and I was expecting something with 960 processor units, and about 1.5 gflops.

ATI/AMD now know that they are ahead of Nvidia, and instead of utilizing the amazing architecture that they have stumbled across, they rather just overclock existing tech.

AMD and Nvidia are playing the same game now, where instead of developing something new, they just selling the same technology only with higher clocks.

I just hope they both can get their act's together and pull something useful out. I do hope that the HD5800 series has about 1400-1600 unit processors on board and the GT300 series has about 400-500 unit processors so as to re-ignite the market, otherwise people won't see any reason to upgrade there graphics.

I think both sides are focusing to much on bandwidth, and that could mean they aren't doing enough with the general tech of the gpu. It's all good and well having 200gb's/s bandwidth, but the gpu's aren't going to be efficient enough to handle the bandwidth and so then you end up with bottle necking and that serves as much purpose as having hair on your tongue...

It isn't really in AMD's best interests to be doing major redesigns on the R770 core at this stage. (Or Nvidia for that matter - with their tech of course - )

Essentially, the 4890 is what the 4870 would have been if they had done it right the first time. All AMD has done is take the R770 core and change its layout a bit, tweak the shaders and add additional power components to remove the bottlenecks present in the 4870. This way they probably won't lose their current yield efficiency as they probably would have if they increased the die size (the G200 series have a massive die size, so their yields and cost per die aren't that great compared to R770). Also, the GTX275 isn't new either (just half a GTX295) so Nv are also trying to make the most of available tech to fill market gaps.

AMD also have their 40nm mainstream parts coming out fairly soon. So they are probably focusing on making a smooth transition to 40nm and getting the parts out on time so they can have a hard launch. Both Nvidia and AMD are rumoured to have DX11 parts due in Q4 of this year (AMD have a bit of a head start with their DX10.1 support), so any resources that could have been used by either side to design something "new" in the interim would see better use in the DX11 chip projects.

I've seen some tech news articles about AMD giving the go-ahead for price cuts on the 4890 seeing that it is sliiightly slower than the GTX275. Let the price wars commence.
 
Hey guys

I just want to make something clear. I never implied that the 4890 is indeed the most powerful processor. That (incredibly bold) statement was made by the manufacturer itself in the press release.

I tried to use this article to show that this isn't exactly the case and I felt that the 285 would be a good competitor in terms of comparison.

but you were stating facts that don't exist... Now I'm not even 18 yet, and I'm close to failing matric so far, but besides my intense lack of intelligence, I can tell you that reporting incorrect information is not good practice.

you must also remember the the HD4890 gpu is in fact the most powerful gpu currectly is Tflops, which does mean it has more computing power which beats the GTX285, so it is the most powerful. they didn't say the gpu that will pull the most FPS, wording is key with these large companies you must remember :)

Who cares about Tflops? I mean sorry but the 4890 just sucks ass have you seen the power pull when gaming? Even a 285 does not pull that much juice! The future is Green IT!

@ Killa yes it is the 275.

I did not say that Tflops was the most important thing! you getting me wrong here, what I was saying was that Tflops indicate the power of the processors computing power, thus because the HD4890 has 1.36Tflops, that makes it the most powerful gpu in sheer computing terms. But that doesn't make it a great performer because it doesn't have many texture units and the fact that it's very software reliant(which amd pays monkeys to code) makes it hard to release all that power.

The thing is, this GPU runs at high volts, it's got a few million more transistors and it's ram runs at higher clocks. all this means that to make the GPU stable, a shyte load of power is needed to feed almost a billion transistors! that's why the power usage is high... However, as soon as AMD goes to 40nm die size, the high power consumption should go down :).

the one thing that's irritating me is why AMD isn't adding more texture units, if they made the HD4890 with 50-60 texture units, the performance will jump quite substantially as there's enough(800) SPE's to do the other work
 
i'll stick to nvidia cards, well my salary won't stick to either right now :D
 
I wont buy another ATi card again until AMD sort out the Rendering issues. View distance is a b*tch to say the least with ATi. My eyes are on that GTX 275 :D Actually screw that where are the new cards?? hmmmmm

I think you mistaken... in ATI's history ATI has always released a intermeditary card that boasts new design to the new cores RV790 (4890) which is usually a optimised, better designed gpu over the older core RV770 XT but not necessary better performing GPU...

The next card they release with the new RV790 should boast significant difference over the current generation cards :)

It's usually Nvidia that drags their feet on new core's

I've had both ATi and nVidia cards in my day and simply prefer ATi/AMD.
nVdia are d i c k s!!! Look how much they sold the 280GTX for until the 4870 was released. Be glad that ATi are competing. Otherwise we will always pay such ridiculous prices.
