ATI Radeon 4890 in April?

Whoa, at $199-$249 it's going to push all the prices for ATI's other cards down, way down.

Glad I'm holding off on upgrading for now.
 
price doesn't seem low to me

You can get a 1GB 4870 right now for $200 and the link says it will be out in April. And it looks like a higher clocked/faster ram 4870, not a new design
 
Hm, any info on the RV790 core? It would be interesting if this core is indeed an RV770 core with the extra ALUs enabled (these were basically used for fine-grained ALU redundancy, i.e in layman terms the RV770 sports extra ALU blocks up to 960 ALUs IIRC to improve yields) If this is true, yields must be VERY good on the RV770 cores that even the redundancy techniques aren't needed.. This could bring some serious competition to the GTX285.
 
So what is this, a new GPU or just higher voltage and clocks? If it's the latter, it's not impressing. Would be more like a 4870+ or something. 🙂
 
I wouldn't be shocked if this was true... look what the 4870 did to the GTX260 and GTX280 price, what the 4850 did to 9800 pricing. Regardless of what the Nvidia fanboys want to say, the 48x0 card MUST be cheaper to produce. AMD can make money and ship a good volume of cards at that price. Not sure what other goodies might be in the 4890, my 4880 runs at 1150MHz on the memory and 820 on the core. Unless they add more stuff to the core I'd think we'd be able to get a decent idea of what to expect out of the 4890 with just a decent overclock on the 4870.
 
I thought AMD reported their GPU division wasn't making money ? Or are you thinking they are losing less money than NV? (which would still be considered proof positive of your assertion IMO)
 
Hmm, might be tempting to bump my 4870 512MB to this 4890 card over waiting another few months for the 5xx0 series. Course, at the prices AMD targets, I could probably do both without financial difficulty.

ati made money in q3, dunno about q4
 
Here's a quick comparison I did with the new clock speeds.

Crysis Warhead - All Gamer ( Enthusiast Shaders )

850/3900
DirectX 10 CUSTOM 2X @ Map: ambush @ 0 1680 x 1050 AA 0xx
==> Framerate [ Min: 28.30 Max: 47.17 Avg: 37.27 ]

750/3600
==> Framerate [ Min: 24.59 Max: 41.51 Avg: 33.04 ]

The GTX285 scored an avg of 38.5 with the same settings in the Anandtech review, of course that's with a i7.

It looks like a nice 13% jump, but it's not going to be enough in titles ATi does poorly in now. Also the increase in voltage more than likely means there's going to be less overclocking headroom. Hopefully ATi has more than just higher clocks in this card.

Hey it could be 1000 shaders too 😀😉
 
The HD 4870 already overclocks to those speeds, so I'm not too impressed. Like Jared said, it comes down to the shader count.
 
Where are they getting the 20% faster than the 4870 figure from? The clock speeds are only 13% faster and the memory 8% faster.

wont those apply to the current cards as well?

If it's from drivers it more than likely will yes. Which meand the 4870 and other cards will not only drop in price with this new card but also get a decent improvement in performance. I know I'll probably pick up a couple 4870s for cheap
 
well, rv770 actually has 900 shaders on the chip with 100 used for increasing the yields, maybe this one has a couple of them enabled, that would explain the +20% performance increase compared to the 4870

Actually ATi is the only part of AMD that is profitable at the moment.

As has been pointed out already, there could be more shaders.
 
Looks like this chip is based on 55nm, seeing at its vcore is at 1.3V where as for 40nm chips the maximum is 1.2V according to TSMC specifications.
