The chips have a 1.1ns memory access time, which corresponds to 900 (1800 effective) MHz.Īs is evident from the above photographs, these cards have a new design that has very little to do with previous ATI cards. The ATI RADEON 2400 XT reference card has 256 MB of GDDR3 SDRAM allocated in four chips on the front and back sides of the PCB. The Samsung memory chip have a 1.2ns memory access time, which corresponds to 800 (1600 effective) MHz.

The Sapphire RADEON 2600 PRO has 256 MB of GDDR3 SDRAM allocated in four chips on the front side of the PCB. The Hynix memory chips are GDDR2 and have a 2.5 ns memory access time, which means they operate at 400 (800 effective) MHz. The PowerColor RADEON 2600 PRO has 256 MB of GDDR2 SDRAM allocated in eight memory chips which are located on the front and back of the PCB. The Qimonda (Infineon) memory chips are GDDR2 and have a 2.0ns memory access time, meaning they operate at 500 (1000 effective) MHz. The HIS RADEON 2600 PRO has 256 MB of GDDR2 SDRAM made up by combining eight memory chips located on the front and back sides of the PCB. The chips have a 0.9 ns memory access time, which means they operate at 1100 (2200 effective) MHz. The Samsung memory chips are manufactured by Samsung and are GDDR4. The ATI Radeon 2600 XT has 256 MB of GDDR4 SDRAM comprised made up by four memory chips located on the front side of the PCB. Sapphire RADEON 2600 PRO (RV630) 256MB GDDR3 PCI-E Memory clock rate (physical (effective)): 414 (828) MHz (nominal - 400 (800) MHz)ĭimensions: 170x100x15 mm (the last figure is the maximum thickness of a graphics card). PowerColor RADEON 2600 PRO (RV630) 256MB GDDR2 PCI-E Multi-GPU operation: CrossFire (Software). Memory clock rate (physical (effective)): 530 (1060) MHz (nominal - 400 (800) MHz)ĭimensions: 170x100x32 mm (the last figure is the maximum thickness of a graphics card).
HIS RADEON 2600 PRO (RV630) IceQ III Turbo 256MB GDDR2 PCI-E Multi-GPU operation: CrossFire (integrated into GPU). Output connectors: 2xDVI (1xHDMI via an adapter), TV-Out. Memory clock rate (physical (effective)): 1100 (2200) MHz (nominal - 1100 (2200) MHz)ĭimensions: 210x100x15 mm (the last figure is the maximum thickness of a graphics card).
Graphics Cards ATI RADEON 2600 XT (RV630) 256MB GDDR4 PCI-E It is important to note that Alexei Nikolaychuk, the author of RivaTuner, has already added support for these new products to his utility: RADEON 2400 XT This article will not focus solely on the products themselves, but will take a stronger look at the architectures behind these cards.
Two of the cards are reference cards, and the three other cards are from Sapphire, TUL, and HIS. Today we are testing five graphics cards. These are the various cards flavors the GPUs come in: In short, the new RV610 GPU along with the RV630 GPU have a number of cards based on them. In the first part of this article we covered all of the architectural details of the RV610 and the RV630 GPUs.
