CPU Mini Review

Mini Review The Ryzen R5 1400 is a high-end CPU based on AMD's 14nm, Zen microarchitecture. It offers 4 physical cores (8 logical), initially clocked at 3.2GHz, which may go up to 3.4GHz using Turbo Boost. It has an unlocked multiplier therefore it can be overclocked using traditional methods. It has 8MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 65W. It is on par with competitor processors. Among its many features, Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It doesn't feature an integrated GPU. This CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC. Core i7-880 Quad 3.06GHz is a high-end CPU based on the 45nm, Nehalem architecture. <br/> <br/> It offers 4 Physical Cores (8 Logical), initially clocked at 3.06GHz, which may go up to 3.73GHz and 8MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor DOES NOT integrated any graphics and has a rated board TDP of 95W. <br/> <br/> Its performance is very good and sufficient for any of today's games.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Ryzen R5 1400 is massively better than the Intel Core i7-880 Quad 3.06GHz 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.

Both the Ryzen R5 1400 and the Core i7-880 Quad 3.06GHz were released at the same time, so are likely to be quite similar.

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 Ryzen R5 1400 and the Core i7-880 Quad both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the AMD Ryzen R5 1400 and the Intel Core i7-880 Quad 3.06GHz have the same number of threads. Both the Ryzen R5 1400 and the Core i7-880 Quad use hyperthreading. The Ryzen R5 1400 has 2 logical threads per physical core and the Core i7-880 Quad has 2.

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 R5 1400 and Core i7-880 Quad 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 R5 1400 has a 0.44 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 .

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 <span class='gpu1Mention'>Ryzen R5 1400</span> has a 1024 KB bigger L2 cache than the <span class='gpu2Mention'>Core i7-880 Quad</span>, and the two CPUs have the same L3 cache size, so the <span class='gpu1Mention'>Ryzen R5 1400</span> 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.
