CPU Mini Review

Mini Review Core i3-3115C 2.5GHz is an extremely energy efficient CPU based on the 22nm, Ivy Bridge architecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), clocked at 2.5GHz and 4MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and HyperThreading</b> are activated. <br/> <br/> The processor DOES NOT integrated any graphics. and has a rated board TDP of 25W. <br/> <br/> It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem. Opteron is AMD's x86 server and workstation processor line, and was the first processor to implement 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 8- and 12-core Socket G34 Opterons, code-named Magny-Cours.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i3-3115C 2.5GHz is noticeably better than the AMD Opteron 2381 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 Core i3-3115C 2.5GHz and the Opteron 2381 HE were released at the same time, so are likely to be quite similar.

The 4 has 2 more cores than the Core i3-3115C 2.5GHz. { 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 Core i3-3115C 2.5GHz and Opteron 2381 HE 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 Core i3-3115C 2.5GHz and the Opteron 2381 HE both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 Core i3-3115C 2.5GHz and the Opteron 2381 HE have the same L2 cache size, but the <span class='gpu2Mention'>Opteron 2381 HE</span> has a 3 MB bigger L3 cache, so in this area, it wins out over the <span class='gpu1Mention'>Core i3-3115C 2.5GHz</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.
