Re: ATi 7000 series delayed till Q1 2012
Some more info
Goggle translate in action xD
1: Tahiti or RADEON HD 7900 with dual ACE or dual geometry engine.
2: under the jurisdiction of each ACE 16 GNC QUAD SIMD
3: a total of 8 Render back-end, or 32 week period to complete the color OP, 128 个 Z-Stencil OP.
4: two read-write cache is 768KiB; every 4 CU share 16KiB L1 instruction cache 32 KiB L1 data cache.
5: 384-bit GDDR5 memory bus bandwidth of up to 264GiB / s
6: using PCI-Express 3.0 bus
7: 4.3 billion transistors.
*Support DX11.1 Support DX11.1
*Similar megatexture a special presentation of Partially Resident Textures (PRT) technology, but this is a hardware implementation, including mapping, filtering and other operations, texture sizes up to 32 TiB (128KiB ^ 3 * 128-bit).
*Tessellation part is clearly up to Gen8 (6900) four times the performance
*Anisotropic Filtering is basically and 6900, but the new improved high-frequency texture flickering problems.
*Double-precision performance of 947 GFLOPS, to achieve the DDR, SRAM full ECC protection.
*Multimedia instruction, the introduction of QSAD, MQSAD, each cycle can be achieved for each CU 256 pixels perform SAD operation, the entire down the equivalent of 7.6 Tera pixels per second.
*Software, WinZip 16.5 will offer OpenCL support (eg AES), which is also described in the slide
