CPU Mini Review

Mini Review Penryn is the code name of a processor from Intel that is sold in varying configurations as Core 2 Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron. During development, Penryn was the Intel code name for the 2007/2008 "Tick" of Intel's Tick-Tock cycle which shrunk Merom to 45 nanometers as CPUID model 23. The term Penryn is sometimes used to refer to all 45 nm chips with the Core architecture. Chips with Penryn architecture come in two sizes, with 6 MiB and 3 MiB L2 cache. Low power versions of Penryn are known as the Penryn processor. The smaller version is commonly called Penryn-3M and is used for the single-core processors. The Penryn-QC quad-cores are made from two chips with two cores and 6 MB of cache per chip. The desktop version of Penryn is Wolfdale and the dual-socket server version is Wolfdale-DP. Penryn-QC is related to Yorkfield on the desktop and Harpertown in servers. The MP server Dunnington chip is a more distant relative based on a different chip but using the same 45 nm Core microarchitecture. Penryn was replaced by the Nehalem based Arrandale (dual core) and Clarksfield (quad core). Turion II Neo K625 is a Dual core mobile CPU based on the 45 nm Geneva Core. <br/> It features 2 cores, clocked 1.5GHz and the fastest supported memory is DDR3-1066. <br/> Its performance is below the average but decent enough to run most games from medium to high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require very reduced settings to be played optimally.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Turion II Neo K625 is noticeably better than the Intel Core 2 Solo ULV SU3500 1.4GHz 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 Core 2 Solo ULV SU3500 1.4GHz and the Turion II Neo K625 were released at the same time, so are likely to be quite similar.

The 2 has 1 more core than the Core 2 Solo. However, while the 2 will probably perform better than the Core 2 Solo, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. { Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

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 Solo and Turion II Neo 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 Turion II Neo has a 0.1 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 <span class='gpu1Mention'>Core 2 Solo</span> has a 1024 KB bigger L2 cache than the <span class='gpu2Mention'>Turion II Neo</span>, but neither of the CPUs have L3 caches, so the <span class='gpu1Mention'>Core 2 Solo</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.
