In terms of overall gaming performance, the AMD APU A4-3320M Dual-Core is noticeably better than the Intel Core 2 Duo U7600 1.2GHz 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 APU A4-3320M Dual-Core was released less than a year after the Core 2 Duo, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core 2 Duo and the APU A4-3320M Dual-Core 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, the Core 2 Duo and the APU A4-3320M Dual-Core may still be able to run slightly older games fairly effectively.

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 2 Duo and APU A4-3320M Dual-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 APU A4-3320M Dual-Core has a 0.8 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 probably a good indicator that the is superior.

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 2 Duo and the APU A4-3320M Dual-Core have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the APU A4-3320M Dual-Core has a 128 KB bigger L1 cache, so would probably provide better performance than the Core 2 Duo, at least 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 Core 2 Duo has a 25 Watt lower Maximum TDP than the APU A4-3320M Dual-Core. However, the APU A4-3320M Dual-Core was created with a 33 nm smaller manufacturing technology. Overall, by taking both into account, the APU A4-3320M Dual-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

The APU A4-3320M Dual-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 Core 2 Duo, 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 ReviewMerom is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M based Yonah processor. Merom has product code 80537, which is shared with Merom-2M and Merom-L that are very similar but have a smaller L2 cache. Merom-L has only one processor core and a different CPUID model. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom has subsequently been replaced by Penryn.The so-called AMD Accelerated Processing Unit (APU) has a 32nm manufacturing process and can take care of a long-battery-life. It doesn't only have the (standard) virtualization technology feature (for improvements in virtualization software like Virtual PC 2007), but also has virus protection that prevents bits, which represent malicious code, getting executed in program data memory. Moreover it includes the integrated Radeon HD 6480G GPU that runs at a core clock of 444 MHz and has 240 shader units; a nice on-chip peripheral! Talking about memory support: I'm sure we still don't need RAM with a higher data rate than 1333 MT/s in games these days (1600 Mt/s might give a little frame rate increase in some cases) and let DDR3 1333 be the max. support of this, I would say, average mobile CPU. You can make a nice setup with it!
