CPU Mini Review

Mini Review Opteron is AMD's x86 server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003 with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007 featuring a new quad-core configuration. The most-recently released Opteron CPUs are the Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively. Pentium G622 2.6GHz is a budget processor based on the 32nm, Sandy Bridge architecture. <br/> <br/> It offers 2 Physical Cores (2 Logical), clocked at 2.6GHz and 3MB of L3 Cache. <br/> Among its many features, <b>Virtualization</b> is activated. <br/> <br/> The processor integrates very weak Graphics called <b>Intel HD Graphics Desktop (Bay Trail)</b>, with 6 Execution Units, initially clocked at 850MHz and that go up to 1100MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor. <br/> Both the processor and integrated graphics have a rated board TDP of 65W. <br/> <br/> It offers average performance. This means it will become a bottleneck in some demanding applications.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Pentium G622 2.6GHz is noticeably better than the AMD Opteron 8374 HE when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the Opteron 8374 HE and the Pentium G622 2.6GHz were released at the same time, so are likely to be quite similar.

The 4 has 2 more cores than the Pentium G622 2.6GHz. { With 4 cores, the 4 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Opteron 8374 HE and Pentium G622 2.6GHz are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Pentium G622 2.6GHz has a 0.4 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is enough that it possibly indicates the superiority of the 4.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The Opteron 8374 HE and the Pentium G622 2.6GHz have the same L2 cache size, but the <span class='gpu1Mention'>Opteron 8374 HE</span> has a 6141 MB bigger L3 cache, so in this area, it wins out over the <span class='gpu2Mention'>Pentium G622 2.6GHz</span>.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.
