| Pemalite said: AMD will probably do something similar to what they did on the old 780G type chipsets where manufacturers would solder some Ram to the motherboard for the GPU to use as a "cache" where it's memory pools in system memory and the motherboards memory could be accessed and used in tandem or individually depending on needs or user settings. Besides, the greatest issue with APU's is generally memory bandwidth, 128bit of GDDR5 is still nothing to sneeze at and certainly far better than the 64bit of DDR3 that the 780G chipsets used. Plus having 256bit memory interface would require more layers on the PCB, hence driving up costs and AMD *is* targeting a cost sensitive market with it's APU's, better to go with 64bit or 128bit and clock the memory chips higher. |
I'd definitely pick up an ultra-thin version with touch screen capability, it'd be good for portable ultrabook type devices for sure. It's just that the weakness of APUs are the memory bandwidth for GPU use and the performance would skyrocket with 256bit since we'd be talking about 8X the bandwidth at the same clock instead of just 4x compared to DDR3 on 64bit contoller. :(
PS: Also hope they don't use GDDR5 but are all DDR4 instead, GDDR5 sounds like a terrible idea TBH.
