AMD: K10 (Stars)

CPU Charts 2012: 86 Processors From AMD And Intel, Tested
By , Achim Roos

AMD offers a great many multi-core CPUs built using its K10 architecture. The most modern models are sold under the Athlon II and Phenom II brands. The company code-named each unique configuration of cores and cache using stars, so the architecture is also commonly referred to as Stars as well.

Athlon II CPUs entered the market in 2009, manufactured using 45 nm process technology. They include two to four cores and drop into the Socket AM3 interface. Dual-core versions are branded as Athlon II X2, triple-core models are Athlon II X3, and the quad-core versions are sold as Athlon II X4. The Athlon IIs don't have any L3 cache.

In contrast, Phenom IIs do generally come with up to 6 MB of L3 cache, though AMD decided to get tricky and sell a few Phenom IIs with less or no L3 memory. The 45 nm Phenom II line-up is similarly named to indicate core count: from the dual-core Phenom II X2 to the hexa-core Phenom II X6, which was introduced in 2010.

The most modern Phenom IIs (the Thuban-based Phenom II X6 and Zosma-based Phenom II X4) also sport Turbo Core technology, which automatically overclocks up to half of the processor's cores when thermal conditions allow.

    Sometimes 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.

    Great benchmarks.
    But i want some processors which were legendary overclockers, and representatives of their generation of CPU's, included with a nominal OC :

    intel C2D E7300 : 2.66- > 3.33
    Intel C2Q Q6600 : 2.4- > 3.0ghz
    Intel i5-750 : 2.66 - >3.33

    Its highly likely that a person has owned at least one of these CPU's. I want to know how well these compare to modern processors.

    Thanks Toms, now i know that i can get double the performance and 3/4 the power consumption going from AMD 955 to a Core i5 3570K.

    And please update the Winrar to version 4.2 . The 3.9 you are using is quite old and has poor multithreading.

    I always wish this. Beyond that the AM3 Athlon X2's are still being sold at newegg and the Phenom X2's are not...

    Agreed, maybe just one dual core and one quad? q9550 and e6850? not that I still own both of those or anything...

    But let's do some math. 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.). So if we start back at Conroe and work our way to present day Ivy Bridge, that's 5 new generations of processors. 1.15^5 = 2.01

    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. Once you take into account faster clock speeds, number of cores, cache sizes, integrated memory controllers, etc. 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.

    I digress. The point being, is I would like to see some more benchies Tom's! Prove me wrong!

    Lot of great info here, but missing Core i3 info leaves a big hole in the data point. Please add.

    I believe the i5-2500K has a 95W TDP instead of 65W.

    This is very Helpful. Now I knew that I did a very good work upgrading to 3470. ;) 
    There should be i3 3220 too. Really wanted to know about that.

    Throw in a Pentium 4 as a reminder to those folks who still think they can run BF3 on a 1.8 GHz Willamette.


    And as for fun, there should've been a CPU rendering test. Windows 7 has a function that allows a CPU do to DX10 graphics, completely bypassing the GPU. The only obviously issue that CPUs are terrible compared to GPUs when it comes to graphics.

    Agreed, 1 Core 2 duo/quad 65nm & Core 2 duo/quad 45nm.

    There is no need to bench 2600K/2700K & Core i5-2300/Core i5-2310, just one of the 2 set will do, because we all know their performance is close to identical.

    "Of course, as we all know now, the Piledriver-based Vishera parts are available, and have been since late October. Worry not; we are in the process of running several more processors based on Piledriver through the same suite of benchmarks, and will be updating the charts soon"

    Sorry, didn't get to read that :D
