The memory controller had to be adapted to the modified cache hierarchy and optimized.ĭue to the shared 元 cache, the cores can communicate without going through the relatively slow main memory together normally.Ī detour is in these processors only necessary if the shared cache is not sufficient or the data for other reasons has already been transferred to the main memory.Ī revised floating point unit is to increase the Gleitkommadurchsatz strong.įurthermore, advanced power management techniques with separate supply lines for the individual processor cores and the memory controller ( "split power planes" ) and a faster HyperTransport link (version 3.0) on newer motherboards are available. With the changeover of production to 45nm now up to six cores were realized and the 元 cache is increased to up to 6 MB.Īt the same time, there is now also models without 元 cache.Ĥ5nm CPUs with the 元 cache cut in IPC ( instructions per clock) better than their 65nm predecessors, while CPUs have a lower IPC on average without 元 cache.Ĭompared to the crossbar K9 had to be extended in order to respond more cores. On a The up to four cores were housed with their dedicated (ie dedicated ) caches up to two memory controllers, crossbar and from all cores shared 2 MiB large 元 cache in the manufacture in 65nm process. The K10 microarchitecture is designed from the ground up as a multi-core processor.
#Amd k10 45nm code
The K10 microarchitecture, formerly known erroneously as AMD K8L, but this is the code name of a low-power variant of the K8 microarchitecture. The K10 micro-architecture is still based on the AMD64 microarchitecture used for some time. I digress.AMD K10 (aka "AMD Next Generation Processor Technology " or "stars" ) is the code name of a micro-architecture for microprocessors from AMD, which has the K8 and K9 - generation supplemented and replaced the medium term.
#Amd k10 45nm software
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.
Once you take into account faster clock speeds, number of cores, cache sizes, integrated memory controllers, etc. 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.
