In terms of overall gaming performance, the AMD Opteron 6344 is noticeably better than the AMD Ryzen R7 1700 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 Ryzen R7 1700 was released over three years more recently than the Opteron 6344, and so the Ryzen R7 1700 is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Opteron 6344 when running the latest games.

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 Opteron 6344 has 4 more cores than the Ryzen R7 1700. 12 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the Ryzen R7 1700 is more than enough for gaming purposes. However, if you intend on running a server with the Opteron 6344, it would seem to be a decent choice.

The Ryzen R7 1700 has 4 more threads than the Opteron 6344. The Opteron 6344 has one thread per physical core, whereas the Ryzen R7 1700 uses hyperthreading and has 2 logical threads per physical core.

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 Ryzen R7 1700 and Opteron 6344 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 Ryzen R7 1700 has a 0.4 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 6344.

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 6344 has a 8192 KB bigger L2 cache than the Ryzen R7 1700, and the two CPUs have the same L3 cache size, so the Opteron 6344 wins out in this area with its larger L2 cache.

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 Ryzen R7 1700 has a 50 Watt lower Maximum TDP than the Opteron 6344, and was created with a 18 nm smaller manufacturing technology. What this means is the Ryzen R7 1700 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).

CPU Mini Review

Mini ReviewThe AMD Ryzen 7 1700 8-Core 3.7GHz is a high-end CPU based on the 14nm Zen micro architecture. It offers 8 physical cores (16 threads), initially clocked at 3.0 GHz base clock, rising to 3.7 GHz with boost clock. It has an unlocked multiplier for overclocking, and 16MB of L3 Cache. Among its many features are Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost. This CPU is likely to offer exceptional computational performance and will not be the bottleneck in any modern gaming PC. It will be able to play all modern games comfortably on high/ultra graphics performance without being a hindrance to the accompanying GPU.Opteron 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.
