A10-5800K vs. Core i3-3220 CPU Review

The Reviewed CPUs

In the tables below, we compare the main features of the CPUs included in our review. The new A10-5800K finally brings support for the SSE4 instruction set (both SSE4.1 and SSE4.2), and it also supports the AVX instruction set. More importantly, it has a “turbo clock” technology, which was not available on the previous generation and is not available on Intel’s Core i3 processor line. The Intel CPUs included in our review are dual-core, but since they support Hyper-Threading (HT) technology, which simulates one additional core per CPU physical core, the operating system “sees” these CPUs as having four cores.

It is important to understand that with the second-generation APUs from AMD, each pair of CPU cores share the same front-end engine (i.e., the fetch unit, the L1 instruction cache, and the instruction decoders). So, each pair of CPU cores is part of the same “module,” and the A10-5800K is comprised of two of these modules. This concept was introduced with the AMD “Bulldozer” architecture, used on AMD’s FX processor line, and adopted on the “Piledriver” architecture used by the second-generation APUs. With the other CPUs included in our review, each core is a complete CPU, each with its own front-end engine.

Prices were researched at Newegg.com on the day we published this review. TDP stands for Thermal Design Power and states the maximum amount of heat the CPU can dissipate. The CPU cooler must be capable of dissipating at least this amount of heat.
