Corsair Explains The Impact of RAM Speed On Kaveri

[xelosia]

AMD’s Kaveri APU is upon us, and the technology is, depending on your perspective, pretty impressive. Kaveri utilizes substantially updated Steamroller x86 cores, offering up to 20% better IPC, but the selling point is the new GPU half and how it interacts with the CPU. Kaveri’s graphics cores utilize the most recent version of their GCN architecture, as found on their top of the line Radeon R9 290X. That’s before even taking into account AMD’s heterogenous system architecture, which completely unifies the system memory space between the CPU and GPU. Kaveri is, at least technologically, a very big dea

Very well explained, as I always said difference between 1600 and 1866 is relatively big, but between 1866 and 2133/2400 is practically null.

Great read and very well explained

If you compare it in that step format then yes its null. But think about how people actually use memory. They dont buy 1600, then 1866 then 2133 then 2400. So it should be compared as if 1600 is baseline cheap ddr3 memory. 1600 vs 1866 1600 vs 2133 1600 vs 2400. So then you check your percentage gains as show in the last chart. So you would gain 21% on average if you go with 2400 vs cheap 1600. Vs a 14% gain with 2133. That 7% for a few more $$ isnt null. Just my thoughts.

Maybe I didn't express myself well, what I meant to say is that if you have 1866MHz memory stick you really don't need to go for 2133/2400, because the performance difference is not that big.

That is a very good answer Smik! cause i plan on using my same memory when i get a new board!
