and more importantly what software will be used with the CPUs the real world performance difference could be almost nothing to somewhere around 10-15x as fast. 128-bit values per cycle, faster instruction decoding) this allows the CPU to process up to two 128-bit SSE instructions per cycle. The width of AMD Floating Point unit was increased to 128 bits. Once you take into account faster clock speeds, number of cores, cache sizes, integrated memory controllers, etc. Recent generations of K10 families are built on more modern 0.045 process, which allows better CPU frequency scaling. Which means that an Ivy Bridge CPU at the same speed as a Conroe CPU (2006ish) is about 2x as fast per clock cycle, on average. So if we start back at Conroe and work our way to present day Ivy Bridge, that's 5 new generations of processors. Just for a rough order of magnitude I figure an average of 15% increase in performance per clock cycle, per generation (not including clock speed, number of cores, etc.). AmdfangirlSometimes I wish you updated legacy CPUs like the Core 2 Duo or even perhaps the Athlon 64 X2 series, just one or two models so that people upgrading can have an idea how much faster the CPU is in relation to their new purchase.Īgreed, maybe just one dual core and one quad? q9550 and e6850? not that I still own both of those or anything.īut let's do some math.
