I reckon the 5770 will be 4890 performance, when you take power consumption into consideration and most likely awesome overclocking, it will win :)

I base this on the fact that it has more SPs, ROPs, and TMUs.

Only thing it's lacking is the memory bandwidth department, but I don't think this will cripple it too much

5750 has an unusual egg shaped cooler lol

some blurb:


The alleged reference model has a relatively short board and sports a dual-slot design with a teardrop-shaped cooling system slapped on it. Like the 5800 series, it features DirectX 11 support, GDDR5 memory (but on a 128-bit bus and clocked at 1150MHz), and the same port arrangement -- two DVI, one DisplayPort, and one HDMI. The card is also equipped with 1120 stream processors and a 700MHz core clock, according to GPU-Z.

In terms of performance, the new Radeon HD 5750 manages to beat both the HD 4850 and the GTS 250 when running 3DMark06 and 3DMark Vantage's synthetic tests -- although by small margins. We'll of course have to reserve judgment until we can put this card to the test in real-world scenarios, but it seems the Radeon HD 5750 could give Nvidia's GeForce GTS 250 a run for its money when it launches (presumably) later this month.

No certain date but rumour all say between 12th and 22nd so it is out in time for the Windows 7 launch.

Also the benchies that show it just barely sqeezing past a GTS250 look like complete bobbins to me, how can a card that is clocked higher, has more shaders, more TMU's, and more ROPs than a 4870/4890 only be as fast as a 4850/GTS250.

The bandwidth (from the 128bit bus) won't limit it that much, especially when its memory stock clock is 1GHz+ over the 4870.

4850 = 256bit (32bytes) x 2GHz = 64GB/s

5850 = 128bit (16bytes) x 4.6GHz = 73.6GB/s

4870 = 256bit (32bytes) x 3.6GHz = 115GB/s

Benchies were for 5750 which has less TMUs and only 16 ROPs apparently.

Also it looks like the 5750/5770/5850/5870 all share the exact same .4ns memory so expect 1200mhz or so overclocks.

Thought the idea was the the 5850 would use cheaper memory and not the same as the 5870, is this not the case?

Perhaps memory overclocking will really help with the limited 128bit memory interface on the 5750/70 cards. Just hope they can be overvolted otherwise the prospects for these cards are not quite as good as I would hope.

I think the 5770 will have to be more than just increased clock speed to justify its price though. A bump in the number of ROPS etc would definately be beneficial.

There ia a pic of a Asus EAH5770 Voltage tweak : on xs forums so i might get that
