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?

To bad they didn't publish the results.

HD 7830?
I hope so as I am looking to up-grade my 6850's cause they only have 1gb of memory and a 7850 is a little too pricy for me right now.

HD 7830?
AMD is not that intelligent. They would name it 7790.

Remember:
Barts LE -> 6790 instead of 6830
Turks Pro -> 6570 instead of 6650
Redwood Pro -> 5570 instead of 5650

Whats the point?

256 bit memory bus serving a gpu slower than 7770?

if it's a 256bit bus it'd probably end up as 7830 if anything, could be a fluke.

Has twice the memory bus width of the 7770, and 128 more stream processors. Not entirely sure how that equated to slower. Most likely a 7830 if they do it on a smart naming scheme due to 2GBs of ram and the 256 bit bus.

Doesnt 7770 run at 1ghz versus this one running at 860mhz?

So it has memory bandwidth equal to that of 7870 and the gpu power slightly higher than 7770.

This is all speculation.
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.

You can call it whatever you want, its still a pointless product. I wouldnt pay any more for this than i would pay for 7770.

edit: also look at the picture it says 256 bit memory bus

Since when are GPUs only about clock speeds?
The 7770 only has 16ROPs while a 7830 could potentially have 32ROPs like in this card.

I'm not one to judge a book by its cover, but that PCB looks cheap as helllll. I have $40 VGA cards from the early 2000's that look more well put together.

Doesn't matter what the screenshot says, if it's a mix up and the gpu used (and shipped by AMD) was intended as an OEM cheapie, the final 'official' configuration is unknown and probably variable, and subject to variable branding depending on card configuration.

They make very cost effective cards as you can see from the pics.

Where is the rumored 7890 that I think may hit the midrange market ?

If that would ever be released i think it would be based on tahiti not picairn.

Im not sure about the tahiti being used for the 7800 series since its Pictarin I believe tahiti is totally reserved for the 7900 series

No it's the other way around it's going to be the 7980 high end card & the dual GPU's will be base on that card...

















...Joke! :laugh:
