In terms of overall gaming performance, the Intel Core i7-2630QM 4-Core 2.0GHz is massively better than the AMD Athlon II M340 Dual-Core 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.

The Core i7-2630QM 4-Core was released less than a year after the Athlon II M340, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i7-2630QM 4-Core has 2 more cores than the Athlon II M340. With 4 cores, the Core i7-2630QM 4-Core 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 Athlon II M340 and Core i7-2630QM 4-Core 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 Athlon II M340 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 Athlon II M340 and the Core i7-2630QM 4-Core have the same L2 cache size, but the Athlon II M340 does not appear to have an L3 cache, so the Core i7-2630QM 4-Core definitely wins out 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.

The Athlon II M340 has a 10 Watt lower Maximum TDP than the Core i7-2630QM 4-Core. However, the Core i7-2630QM 4-Core was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Core i7-2630QM 4-Core is likely the CPU with the lower heat production and power requirements, by a small amount.

The Core i7-2630QM 4-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Athlon II M340, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewThe AMD Athlon II Dual-Core Mobile M340 is an entry level Dual Core CPU by AMD for laptops with an integrated dual channel DDR2 memory controller (400MHz). The core was named Caspian and based on the K10 architecture.
The performance of the Athlon II M300 is comparable to an old Merom 1.8 Ghz Celeron Dual-Core T3000 and can be compared to cheap Celeron Dual Core models by Intel. The Athlon II series has the advantage of Virtualisation and 64-bit processing support
Core i7-2630QM 4-Core 2.0GHz is a high-end mobile CPU based on the 32nm, Sandy Bridge architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 2.0GHz, which may go up to 2.9GHz and 6MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates relatively weak Graphics called Intel HD i7 2630QM, with 12 Execution Units, initially clocked at 650MHz and that go up to 1100MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 45W.

Its performance is very good and sufficient for any of today's games.
