Considerations for Choosing a CPU

Section Link

Core Count

Intel's Core i5-1140G7 CPUs have 4 cores.

We found that, in general, more cores do provide better performance in professional tools and when running multiple applications simultaneously.

Increased core counts can improve the performance of games and professional tools that use them. Most modern games don't benefit from having more than 6–8 cores. Even general apps can benefit from many cores when numerous applications are open simultaneously. Web browsers don't significantly take advantage of multiple cores when loading a single page. However, more CPU cores can improve performance when running demanding web apps in multiple windows.

Intel's 12th generation and newer CPUs have performance cores (P-cores) and efficiency cores (E-cores). The P-cores are comparable to previous generation cores. E-cores are focused on adding additional threads in an energy-efficient manner. They take up much less room on the CPU and generate less heat. However, their smaller cache and minimal interconnect capabilities make them more appropriate for offloading background tasks. E-cores do not support hyper-threading.

CPU Clock Speeds

The Intel Core i5-1140G7 has a 1.80 GHz base frequency and supports a 4.20 GHz single-core max turbo boost frequency.

We've experienced that single-core performance is essential for some games, as many don't take full advantage of multiple cores. Similarly, we have experienced that professional tools depend on high single and multi-core turbo frequencies to maximize their processing speed.

Turbo boost frequencies are only achieved under ideal circumstances. However, with adequate cooling, you may be able to maintain speeds near the max boost frequency.

Higher vs. Lower Base Frequencies

We've found that lower base clock speeds result in lower power consumption.

A CPU's base frequency refers to the clock speed at which its cores run under normal operating conditions. However, the actual clock speed of the CPU can vary depending on the workload and the system power state.

A lower base frequency can lead to better power savings overall since the clock speed decreases when the load is low, resulting in lower power consumption. However, a CPU may run slower than the base frequency to conserve power or reduce heat generation. For example, modern CPUs use technologies like Intel SpeedStep or AMD Cool'n'Quiet to dynamically adjust the CPU's clock speed based on the system's workload and power state.

A CPU with a lower base frequency may generate less heat under normal operating conditions, enabling it to boost some cores to higher frequencies while remaining within its thermal limits. This lower base frequency results in better performance than a CPU with a higher base frequency, which may not be able to sustain its boost frequency for long periods due to thermal throttling. However, this is mostly only relevant if your system's cooling solution can only partially dissipate the heat produced by all cores being fully boosted.

DDR Support

The 1140G7 CPU's fastest supported DDR memory type is LPDDR4x, with a max stock speed of 4267 MHz.

You can exceed these stock speeds officially supported by CPUs when overclocking memory, such as with an XMP profile. Motherboard specifications will indicate their supported overclocked-memory speeds. To be able to overclock DDR memory, your motherboard chipset needs to support memory overclocking.

Faster PC memory can improve game and professional tool performance by reducing the time it takes to perform calculations and data operations.

We've experienced that using the quickest RAM may not have as much of an impact as upgrading your CPU and graphics card or adding more RAM.

Cache Size

The Intel Core i5-1140G7 has an L3 cache capacity of 8 MB.

A CPU's cache is a small amount of memory, close to the CPU cores, containing recently used data. An L3 cache capacity of at least 20 MB is ideal for games and professional tool performance.

Games and professional tool performance can improve as cache size increases, as it can reduce delays when retrieving commonly used assets from memory. While nearly any task will use a CPU's cache, our research indicates that a large cache becomes less impactful for general PC usage, such as browsing webpages.

Remember that cache sizes often increase with core counts, so if you want to increase your L3 cache, you may need to get a CPU with more cores.

Overclocking

The 1140G7 does not support overclocking.

Overclocking is mainly relevant for PC gamers who want to maximize their game framerates. CPU overclocking increases frequencies past their default limits. Excellent heat dissipation via fans or another solution is required to maintain system stability while overclocking. While we felt a sense of excitement and anticipation when we pushed the limits of our CPU's performance, it's essential to remember that overclocking comes with the risk of damaging your system components or voiding warranties.

Professional tools can benefit from overclocked frequencies. However, overclocking may introduce some possibility of system instability, which may be less acceptable in business scenarios. We've found out the hard way that losing work due to system instability is a pain.
