Production Radeon HD 7850 Packs 768 Stream Processors
Tom's Hardware Germany found it difficult to explain lower than normal performance of an AFOX-branded Radeon HD 7850 graphics card. Upon looking at its stream processor count in GPU-Z, it was amazed to notice a value of 768, 25% lower than HD 7850 normal count of 1024. Attempts to replace its BIOS did not change the stream processor count, leading them to believe the stream processors were physically disabled. AMD was of little help, and they were redirected to talk to AFOX, which told them that since March, AMD has been shipping Pitcairn chips with 768 stream processor configuration to some OEMs. Could this be a new SKU under works? HD 7790? HD 7830?

Remember:
Barts LE -> 6790 instead of 6830
Turks Pro -> 6570 instead of 6650
Redwood Pro -> 5570 instead of 5650
256 bit memory bus serving a gpu slower than 7770?
But since it's all rolling, I'll throw in mine:
If it's 128 bit, 768 SP, 1GB RAM, then it'll probably be 7790
If it's 256 bit, 768 SP, 2GB RAM (or even 1GB), then it'll probably be 7830.
edit: also look at the picture it says 256 bit memory bus
The 7770 only has 16ROPs while a 7830 could potentially have 32ROPs like in this card.
probably some shoddy Chinese off shore sweatshop operation
...Joke! :laugh:
