CPU Mini Review

Mini Review Core i7-3540M 2-Core 3.0GHz is a high-end mobile processor based on the 22nm, Ivy Bridge microarchitecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), initially clocked at 3.0GHz, which may go up to 3.7GHz and 4MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor integrates mildly powerful Graphics called <b>Intel HD Graphics 4000</b>, with 16 Execution Units, initially clocked at 650MHz and that go up to 1300MHz, 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 35W. <br/> <br/> It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem. Core i5-3320M 2.6GHz is a middle-class mobile processor based on the 22nm, Ivy Bridge architecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), initially clocked at 2.6GHz, which may go up to 3.3GHz and 3MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and Virtualization</b> are activated and the processor has multiplier unlocked. <br/> <br/> The processor integrates mildly powerful Graphics called <b>Intel HD Graphics 4000</b>, with 16 Execution Units, initially clocked at 650MHz and that go up to 1200MHz, 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 35W. <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 Core i7-3540M 2-Core 3.0GHz is significantly better than the Intel Core i5-3320M 2.6GHz 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 i7-3540M 2-Core 3.0GHz and the Core i5-3320M 2.6GHz 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 Core i7-3540M 2-Core and the Core i5-3320M 2.6GHz both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, theCore i7-3540M 2-Core and the Core i5-3320M 2.6GHz may still be able to run slightly older games fairly effectively.

Both the Intel Core i7-3540M 2-Core 3.0GHz and the Intel Core i5-3320M 2.6GHz have the same number of threads. Both the Core i7-3540M 2-Core and the Core i5-3320M 2.6GHz use hyperthreading. The Core i7-3540M 2-Core has 2 logical threads per physical core and the Core i5-3320M 2.6GHz has 2.

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 Core i7-3540M 2-Core and the Core i5-3320M 2.6GHz are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.4 GHz faster base clock rate, the Core i7-3540M 2-Core manages to provide slightly better performance than the <span class='gpu2Mention'>Core i5-3320M 2.6GHz</span>.

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 i7-3540M 2-Core and the Core i5-3320M 2.6GHz have the same L2 cache size, but the <span class='gpu1Mention'>Core i7-3540M 2-Core</span> has a 1 MB bigger L3 cache, so in this area, it wins out over the <span class='gpu2Mention'>Core i5-3320M 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.

Both the Core i7-3540M 2-Core and the Core i5-3320M 2.6GHz have the same TDP of 35 Watts, and were created with the same manufacturing size of 22 nm, which means they will affect your yearly electricity bill about equally.
