When selecting a CPU for gaming, the most important characteristics are the frequency (clock speed), core/thread count, cache size, and supported memory type. Additional considerations like integrated graphics and overclocking needs may also influence your selection.
This article explains the features of Intel's Core i3-1005G1 laptop CPU and how it performs with gaming. We compare the CPU's attributes rather than benchmarks to help you determine which features are most important when selecting a laptop.
When using Intel's Core i3 1005G1 CPU for gaming, you can expect poor game performance. This performance is based on the following characteristics of the CPU and their relevance to the latest graphics-intense games:
- 4 MB of L3 cache is poor for performance
- 2 cores will result in poor performance
- 1.20 GHz base frequency
- 3.40 GHz single-core max turbo boost frequency is mediocre for performance (requires good heat dissipation)
- Max stock DDR4 speed of 3200 MHz can be good for performance
- The 1005G1 also supports LPDDR4, which may have reduced performance compared to DDR4 memory.
- Lack of overclocking support cannot benefit performance
- PCIe 3.0 support can be poor for performance (limits potential of fastest SSDs and GPUs)
- The 1005G1 has integrated graphics support, with the CPU and GPU on a single chip die, known as an APU. However, this performance assessment assumes you will use an internal or external graphics card. Integrated graphics support is mediocre or worse with the latest graphics-intense games.
A CPU's cache is a small amount of memory, close to the CPU cores, containing recently used data.
Games performance can improve as cache size increases, as it will reduce delays when retrieving commonly used game assets from memory.
An L3 cache capacity of at least 20 MB is ideal for game performance.
The Intel Core i3-1005G1 has an L3 cache capacity of 4 MB.
The 1005G1's lackluster 4 MB of L3 cache is poor for performance with the latest graphics-intense games.
Increased core counts can improve the performance of games that use them, but most modern games don't benefit from having more than 6–8 cores. Remember that cache sizes often increase along with core counts, so if you want to increase your L3 cache, you may need to get a CPU with more cores.
Intel's Core i3-1005G1 CPUs have 2 cores.
The 1005G1's limit of 2 cores will result in poor performance with the latest graphics-intense games.
Single-core performance is essential for some games, as many don't take full advantage of multiple cores.
The safest strategy for consistent gaming performance with a laptop is to get a higher base clock speed processor. High base frequencies will ensure that the laptop was designed to adequately cool the CPU at the base frequency. With exceptional cooling, you may be able to maintain speeds near the max boost frequency. However, laptops usually cannot cool CPUs enough to support constant boost frequencies. Turbo boost frequencies are only achieved and sustained under ideal circumstances.
The 1005G1 CPU's lack of support for overclocking cannot benefit performance with the latest graphics-intense games.
The processor has a 1.20 GHz base frequency and supports a 3.40 GHz single-core max turbo frequency.
The 1005G1 has a 1.20 GHz base frequency, which is the speed before boosting. You can reach these base frequencies even without good heat dissipation.
With good heat dissipation, the 1005G1's 3.40 GHz single-core max turbo boost frequency is mediocre for performance with the latest graphics-intense games. You can maintain these frequencies with good heat dissipation.
The 1005G1 CPU's support for DDR4 with a max stock speed of 3200 MHz can be good for performance with the latest graphics-intense games.
The 1005G1 also supports LPDDR4, which may have reduced performance compared to DDR4 memory.
Faster PC memory can improve game performance and frame rates, but using the fastest RAM may not have as much of an impact as upgrading your CPU and graphics card or adding more RAM.
|Processor Name Suffix||Meaning|
|G1||G1-G7 suffixes indicate the graphics capabilities of a processor, with higher numbers being better.|
The 1005G1 model name doesn't have a K or X suffix, which means that it can not be overclocked.
