The New $100 Budget Card - Radeon HD 4770 Review Roundup

[WiCKeD]

"Recently, ATI launched the Radeon HD 4890 using the RV790 GPU, a respun RV770 with a few tweaks and improvements in order to improve its position in the higher end $200+ price bracket. However, most of its sales are in the $100 category and lower price points. Today, ATI delivers a GPU to consumers at that range that NVIDIA can't match.

The Radeon HD 4770 video card that is launching today uses the RV740 GPU, which is the first 40nm GPU in mass production. The GPU consists of 826 million transistors at a core clock of 750MHz, measuring 11mm by 11mm. The Radeon 4770 features 512MB of GDDR5 DRAM clocked at 800MHz, but effectively provides 3.2 Gb/s over a 128-bit bus.

The new GPU has 640 Stream processors, the same number as the Radeon HD 4830 that it will replace. The Radeon 4830 will be quietly phased out since the Radeon 4770 offers better performance at a much lower production cost to AMD. This is offset by higher costs for GDDR5 RAM." - DailyTech

Given that the 4850 is only 90-100 AR, there's not much reason to get a 4770 right now...

Is there any benchies of the 4770 vs 4850 out yet? with the die shrink and GDDR 5 on the 4770 it sounds better...... on paper anyway.

yes, the 4850 wins by a few fps. a few of the links up there have both cards in them.

What if the 4770 OC's better due to the 40nm process the difference in shader could be made up by how much it OC's better then the 4850, if this is even the case

Right now, it’s maxing out the meager maximums in CCC and the stock cards come with a heavier, two slot cooler vs the single slot on the 4850s. It could potentially overclock extremely well, but someone needs to get their hands on one to verify. It looks like it will be a hair off the 4850s, though.
