In terms of overall gaming performance, the AMD Opteron 4280 is massively better than the Intel Core i5-670 3.46GHz 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 Opteron 4280 was released over a year more recently than the Core i5-670 3.46GHz, and so the Opteron 4280 is likely to have better levels of support, and will be more optimized for running the latest games.

The Opteron 4280 has 6 more cores than the Core i5-670 3.46GHz. With 8 cores, the Opteron 4280 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 Opteron 4280 and Core i5-670 3.46GHz 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 i5-670 3.46GHz has a 0.66 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 enough that it possibly indicates the superiority of the Opteron 4280.

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 Opteron 4280 has a 488 KB bigger L2 cache than the Core i5-670 3.46GHz, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 i5-670 3.46GHz has a 22 Watt lower Maximum TDP than the Opteron 4280 (though they were created with the same size 32 nm manufacturing technology). What this means is the Core i5-670 3.46GHz will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The Core i5-670 3.46GHz 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 Opteron 4280, 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 ReviewOpteron 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.Core i5-670 3.46GHz is a performance CPU based on the 45nm, Nehalem architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 3.46GHz, which may go up to 3.73GHz and 4MB of L3 Cache.
Among its many features, Hyper-Threading, Turbo Boost and Virtualization are activated.

The processor integrates very weak Graphics called Intel i5 670, with XX Execution Units, clocked at 733MHz which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 73W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
