CPU Comparison
Intel Core i5-7500 vs Intel Core i3-8100
A side-by-side comparison of specs, performance and value. The Intel Core i5-7500 is a mid-range desktop processor launched in early 2017 as a core component of the 7th Generation Kaby Lake family. Featuring four physical cores without Hyper-Threading, it operates at a base frequency of 3.4 GHz and can boost up to 3.8 GHz. Manufactured on Intel's 14nm process, it fits within a standard 65-watt TDP, ensuring broad compatibility with mainstream cooling solutions. The processor was a popular choice for budget gaming builds and office PCs, offering a slight frequency bump over the i5-7400. It integrates Intel HD 630 graphics, capable of hardware-accelerated 4K video decoding, and supports dual-channel DDR4 memory at 2400 MT/s. While it provides snappy single-thread performance for everyday applications, the lack of Hyper-Threading limits its capability in heavily multi-threaded modern workloads. Utilizing the LGA 1151 socket, the i5-7500 remains a viable option for upgrading older systems, though it is outclassed by newer architectures in both efficiency and core count.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy for everyday office work but struggles with heavy rendering due to 4 threads.
The lack of Hyper-Threading severely limits performance in heavily threaded office applications compared to newer 8-thread budget chips.
Gaming
Adequate for older games but bottlenecks modern GPUs in CPU-heavy titles.
Paired with a strong discrete GPU, it can still handle older eSports titles, but modern AAA games will be heavily CPU bottlenecked.
Virtualization
Limited by core count for running multiple VMs.
4 threads is the absolute minimum for running a modern OS and a single light virtual machine.
Efficiency
65W TDP offers a good balance of power and heat.
The 14nm process is power-hungry compared to modern 7nm or 5nm alternatives, drawing 65W for modest performance.

Our Verdict on Each
A step up from the i5-7400, offering better clocks, but the 4-core/4-thread limitation makes it obsolete for modern heavy multitasking and gaming.
Best for: Upgrading an older LGA 1151 system on a strict budget.
Read the full reviewA landmark chip in 2017 for bringing quad-core computing to the masses, but thoroughly outclassed by modern budget processors in every metric.
Best for: The only justifiable scenario for purchasing an Intel Core i3-8100 today is if you are repairing an existing LGA 1151 v2 system (like an office PC or a hand-me-down) and can find the CPU for under $20 on the used market. Even then, you must consider that the 8100 lacks Hyper-Threading, which severely limits its longevity in modern operating systems that are increasingly optimized for 8 or more threads. If you are building a new system, even the absolute cheapest new motherboard and CPU combo from AMD or Intel's 12th/13th gen will offer exponentially better performance, efficiency, and platform features like PCIe 4.0 or DDR5. Do not buy this CPU for gaming, as the lack of Turbo Boost and Hyper-Threading will cause severe stuttering in modern titles compared to a modern Ryzen 3.
