In terms of overall gaming performance, the Intel Xeon Processor E5607 is noticeably better than the AMD Opteron 8374 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.

The Xeon Processor E5607 was released less than a year after the Opteron 8374 HE, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Opteron 8374 HE and the Xeon Processor E5607 both have 4 cores, which is not likely to be a limiting factor for gaming.

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 8374 HE and Xeon Processor E5607 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 Xeon Processor E5607 has a 0.07 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 Xeon Processor E5607 has a 512 KB bigger L2 cache than the Opteron 8374 HE, but on the other hand, it is the Opteron 8374 HE that has a 6136 MB bigger L3 cache than the Xeon Processor E5607. In this case, the L2 size is probably what counts, so the Xeon Processor E5607 is likely superior 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 Opteron 8374 HE has a 25 Watt lower Maximum TDP than the Xeon Processor E5607. However, the Xeon Processor E5607 was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Xeon Processor E5607 is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

CPU Mini Review

Mini ReviewOpteron is AMD's x86 server and workstation processor line, and was the first processor which supported 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 Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively.Intel Xeon E5607 is a Server CPU part of the Xeon Series continuously released by Intel.
It's based on the Nehalem architecture and the memory controller supports DDR3-800 and DDR3-1066.
The performance though good, falls behind most Intel i5, i7 and since Intel Xeon E5607 wasn't built for gaming purposes it comes at a considerably high price.
