ASUS EAH3650 TOP 256MB Review :: ASUS EAH3650 TOP Features

• 800MHz Core Clock speed
• 1.8GHz memory clock speed
• DirectX 10.1
• 80 Stream Processors
• 55 nanometer process
• 378 million transistors
• 128-bit memory bus
• ROPs  16
• Texture filtering units 8
• Texture address units 16
• Framebuffer 256MB
• Shader Clock 800MHz

The 3650 is based upon ATI’s RV635 chip. The RV635 is the replacement for the HD2600XT that was launched alongside the HD2900XT to be the mid-range card in their lineup. RV630 uses the 55 nanometer process technology from TSMC, ATI’s graphics Fab partner. NVIDIA still uses the 65 nanometer process which allows ATI to use a smaller chip and generate less heat and energy.

The Core clock on the EAH3650 TOP is 800MHz which is 75MHz faster than the default clock of the HD3650 from ATI. This offers a 3.2 Gigapixel fillrate with 16 texture address units and 8 texture filtering units the HD3650 is quite an improvement over the HD2600XT which it replaces. The HD3650 has 120 Stream Processors, which is less than the 320 found on the HD3870 but that is the high end single chip card.

The EAH3650 comes with 256MB of DDR3 memory clocked at 900MHz or 1.8GHz effective. ATI outfits this card with a 128-bit memory bus, meaning that there is a memory bandwidth of 28.8GB/second (900x2x128-bit/8). With 4 outputted pixels (ROPs) in a clock and a fillrate of 6.4 Gigatexels a second a 256-bit memory bus isn’t necessary.

DirectX 10.1 is the latest graphics API (Application Programming Interface) from Microsoft. It introduces new features for anti-aliasing and improves upon Shader Model 4.0 by allowing for better Global Illumination and is fully supported by the EAH 3650 video card. I won’t go into the SM 4.0 versus 4.1 debates, as game developers have struggled to fully use DirectX 10 features, but the card supports it when the game or application requires it.
