The ATI RADEON X700 Series (PCIe)
Like the GeForce 6600 series, ATI's RADEON X700 series is just a midrange variant of the high-end RADEON X800 series that we recently covered. All the features we have come to expect on the RADEON X800 series is mirrored over to the RADEON X700 series with the exception of processing throughput, which has been tailored to fit its price segment. However unlike the GeForce 6600 that had exactly half the processing power of its GeForce 6800 brother, the RADEON X700 series boasts a much higher vertex throughput and is equivalent to the RADEON X800 series in this aspect. The RADEON X700 series have six geometry engines versus three on the GeForce 6600 series. Soon enough, we'll know if ATI's advantage in this department is of any assistance to counter NVIDIA's offerings.
The ATI RADEON X700 Series (PCIe)
| GPU/VPU | ATI RADEON X700 XT | ATI RADEON X700 PRO | ATI RADEON X700 | | Core Code | RV410 | RV410 | RV410 | | Transistor Count | 120 million | 120 million | 120 million | | Manufacturing Process (microns) | 0.11 | 0.11 | 0.11 | | Core Clock | 475MHz | 425MHz | 400MHz | | Vertex Shaders | 6 | 6 | 6 | | Rendering (Pixel) Pipelines | 8 | 8 | 8 | | Texture Units per Pipeline | 1 | 1 | 1 | | Memory Clock | 525MHz (1050MHz DDR3) | 430MHz (860MHz DDR3) | 300MHz (600MHz DDR1) | | DDR Memory Bus | 128-bit | 128-bit | 128-bit | | Memory Bandwidth | 16.8GB/s | 13.8GB/s | 9.6GB/s | | RAMDAC | Dual 400MHz | Dual 400MHz | Dual 400MHz | | TV Output | Int., 1024x768 | Int., 1024x768 | Int., 1024x768 | | TMDS transmitter | Int. 165MHz | Int. 165MHz | Int. 165MHz | | PCI Express Interface | x16 | x16 | x16 | | Molex Power Connectors | NIL | NIL | NIL |
The RADEON X700 series too have undergone a die shrink and utilizes the 0.11-micron process versus the 0.13-micron process for the X800 and even some of the X850 products. This is ATI's second successful VPU part on this manufacturing process after the initial entry-level RADEON X300 series.
