2 7800GT ? Quel interet ? Aucun. Pour ce prix on a 2*7900GT ou une X1900XT... X1900XT power

Ah sauf que la X1900XT coute 470€ et 2*7900GT coutent 600€ ^^

2500E ? 1500 plutot! Ou alor tu te fait arnaquer!

7900gt < x1900xt ?

voila se qu´est la arte graph de la 360

The graphics processing unit (GPU) is a custom ATI R500-based "Xenos"

• 337 million transistors total
• 500 MHz parent GPU (90 nm process, 232 million transistors)
• 500 MHz 10 MB daughter embedded DRAM framebuffer (90 nm process, 105 million transistors)

o NEC designed eDRAM has internal logic for color, alpha blending, Z/stencil buffering, and anti-aliasing.

• 48-way parallel floating-point dynamically-scheduled shader pipelines

o 4 arithmetic logic units per pipe for vertex or pixel shader processing
o Unified shader architecture (This means that each pipeline is capable of running either pixel or vertex shaders.)
o Support for DirectX 9.0 Shader Model 3.0, limited support for future DirectX 10 shader models
o 2 Shader operations per pipe per cycle
o 96 Shader operations per cycle across the entire shader array
o Shader performance: 48 billion (48,000 million) shader operations per second

• 16 Filtered & 16 unfiltered texture samples per clock
• Maximum polygon performance: 500 million triangles per second
• Pixel fillrate: 16 gigasamples per second fillrate using 4X MSAA
• Dot product operations: 9.6 billion per second theoretical

maximum, 33.6 billion per second theoretical maximum when summed with CPU operations.

Erreur, la xBox 360 = à une X1800XT et la PS3 à une 7900GT
