CPU Mini Review

Mini Review The Xeon E5-2690 v2 is an extremely high performance 64-bit 10-core processor with a clock speed of 3.0GHz. <br/> It's based on the Ivy Bridge architecture and the memory controller supports DDR3-800, DDR3-1066, DDR3-1333, DDR3-1600 and DDR3-1866. Xeon E3-1225 v2 is a Server Processor based on the 22nm, Ivy Bridge architecture. <br/> <br/> It offers 4 Physical Cores (4 Logical), initially clocked at 3.2GHz, which may go up to 3.6GHz and 8MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor integrates mildly powerful Graphics called <b>Intel HD Graphics P4000</b>, with 20 Execution Units, initially clocked at 650MHz and that go up to 1250MHz, 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 77W. <br/> <br/> Though not created for gaming purposes, its performance is very good and sufficient for any of today's games.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Xeon E5-2690 v2 is massively better than the Intel Xeon E3-1225 v2 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 Xeon E5-2690 v2 and the Xeon E3-1225 v2 were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The 10 has 6 more cores than the Xeon E3-1225 v2. 10 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The 4 cores in the Xeon E3-1225 v2 is more than enough for gaming purposes. However, if you intend on running a server with the 10, it would seem to be a decent choice.

The Xeon E5-2690 v2 has 16 more threads than the Xeon E3-1225 v2. The Xeon E3-1225 v2 has one thread per physical core, whereas the $strippedName1 uses hyperthreading and has 2 logical threads per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

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 Xeon E5-2690 v2 and Xeon E3-1225 v2 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 Xeon E3-1225 v2 has a 0.2 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. As such, we need to look elsewhere for more reliable comparisons.

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 <span class='gpu2Mention'>Xeon E3-1225 v2</span> has a 768 KB bigger L2 cache than the <span class='gpu1Mention'>Xeon E5-2690 v2</span>, but on the other hand, it is the <span class='gpu1Mention'>Xeon E5-2690 v2</span> that has a 17 MB bigger L3 cache than the <span class='gpu2Mention'>Xeon E3-1225 v2</span>. In this case, the L2 size is probably what counts, so the <span class='gpu2Mention'>Xeon E3-1225 v2</span> is likely superior in this area.

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.
