PowerColor to launch HD4730
AMD is dressing up a new ATI Radeon SKU to go to office soon. The Radeon HD 4730 beats our guesswork, and wits both in one shot. The new SKU is not based on a scaled-down 40 nm RV740 GPU the HD 4770 is based on, but rather on a new RV770 variant, dubbed the RV770CE. This GPU is physically identical to the RV770, and has part of its configuration identical to the RV770LE (Radeon HD 4830), while its memory interface is 128-bit GDDR5 instead of 256-bit GDDR3.
The only explanation we have in store is that perhaps AMD is looking to save on using lesser number of memory chips per board (while not crippling the memory interface), and that RV770 is in healthier stock than the RV740. Pictured below is the PowerColor Radeon HD 4730 PCS, one of the first cards based on the GPU. Other important specifications, such as stream processor count, and clock-speeds are yet to surface. Ideally it should cash-in on a price-segment below that of the Radeon HD 4770.

Late May, 512MB GDDR5 surprise
It looks like there won't be any GDDR3 version of RV740, ATI's first 40nm card. PowerColor has already told us that it plans to launch Radeon HD 4730 card clocked at 700Mz core and with GDDR5 memory. It is not clear at this point, but 4730 might be even based on 55nm RV770LE chip.
The memory will run at 3600MHz and matched with 128-bit interface, it should provide just about enough bandwidth. The card should be available at the end of May and AMD wants to attack Geforce 9600GT 512MB market.
The card should sell for $79 at launch, or $20 less than Radeon HD 4770, and we assume that it should not be that much slower. The cooler on the card comes from Arctic cooling, but we don't really know which one they've chosen.

ง่ายๆเลยมันคือ RV770LE หรือ HD4830 ในมาด GDDR5
แต่โดนลด bit เหลือ 128 bitแทน (ถ้า 256bit แบบเดิม งานเข้าแน่)
จากที่ก่อนหน้านี้คาดกันว่ามันจะป็น RV740 ที่มากับ GDDR3
พออกมาเป็นแบบนี้ทำให้คิดว่ามันอาจจะแรงตาม HD4770 ไม่มากก็ได้
ซึ่ง HD4730 นี่จะมาแข่งกับ GF9600GT แทน (เดิม HD4830 แข่งกันกับ 9800GT ยังสูสีเลย -*-)
โดย PowerColor เปิดราคามาที่ 79$ หรือถูกกว่า HD4770 30$
(เพราะตอนนี้ HD4770 ขายกันที่ 109$ นะครับ ATi ปรับราคาก่อนขายนิดหน่อย)
มาดูกันต่อไป ทั้งราคาเข้าไทย และความแรงของ RV770LE 128bit GDDR5 ตัวนี้กัน
