On Chinese Internet- forum appeared the characteristics of two promising video card ATI radeon HD 6700: HD 6750 and 6770.
First the accelerator HD 6770 (code name barts XT) will obtain:
- Processor, which works at the frequency 900 MHz (HD 5770 � 850 MHz);
- 1280 stream processors (HD 5770 : 800);
- 32 blocks rops (HD 5770 : 16);
- 64 blocks textural addressing (HD 5770 : 36);
- Memory bus length 256 bits (HD 5770 :128 bits);
- GDDR5 Memory, which works at the frequency 1050 MHz (HD 5770 : 1200 MHz).
Peak productivity for ATI radeon HD 6770 is 2,304 teraflops, the memory capacity is 134,4 GB/s, the theoretical maximum fill rate speed 28,8 gigapixel per second, the theoretical textures sampling speed 57,6 giga-Texfirs tree per second. For ATI radeon HD 5770 � these parameters are equal to respectively 1,360 teraflops, 76,8 GB/s , 13,6 giga-pixel per second even 34,0 giga-Texfirs tree per second.
ATI radeon 6750 (Barts pro) is only simpler than its analog. It includes:
- Processor, which works at the frequency 725 MHz (analogous WITH HD 5750);
- 1120 stream processors (HD 5750 : 720);
- 32 blocks ROPS (HD 5750 :16);
- 56 textural addressing blocks (HD 5750 : 36);
- Memory bus length 256 bits (HD :128 bits);
- GDDR5 Memory, which works at the frequency 1000 MHz (HD 5750 : 1150 MHz).
Peak productivity for ATI radeon HD 6750 is 1,624 teraflops, memory capacity 128 GB/s, the theoretical maximum fill rate speed 23,2 giga-pixelit per second, theoretical textures sampling speed 40,6 giga-Texfirs tree per second. For predecessor ATI radeon HD 5750 � these parameters are equal to respectively 1,008 teraflop, 73,6 GB/s, 11,2 giga-pixel per second even 25,2 giga-Texfirs tree per second.
Thus, even the quick comparison of ATI radeon HD 6750 and HD 6770 with their predecessors confirms AMD statement about 2x superiority i.
ATI radeon HD 6770 will require 146 W peak output and 23 W with simple load. ATI radeon HD 6770 will be 114 and 20 W. Related Products :
