CPU Comparison
Intel Core i5-7600 vs Intel Core i3-9300
A side-by-side comparison of specs, performance and value. The Intel Core i5-7600 is a high-end mainstream desktop processor launched in early 2017 as part of the 7th Generation Kaby Lake lineup. Positioned just below the unlocked K-series, it features four physical cores without Hyper-Threading, operating at a base frequency of 3.5 GHz with a maximum turbo boost of 4.1 GHz. This represents the highest clock speeds available on a locked 7th Gen i5 processor. Manufactured on Intel's 14nm process, it maintains a 65-watt TDP, making it easy to cool with standard solutions. The processor integrates Intel HD 630 graphics, providing hardware-accelerated 4K media decoding, and supports dual-channel DDR4 memory at 2400 MT/s. While its high clock speeds deliver excellent single-thread performance for gaming and daily applications, the absence of Hyper-Threading limits its multi-threaded throughput. Utilizing the LGA 1151 socket, the i5-7600 was aimed at users seeking top-tier locked performance, though it was quickly overshadowed by the 6-core 8th Gen processors that followed.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very snappy for daily tasks, but 4 threads limit heavy multitasking.
The 8 MB cache helps keep frequently used office applications responsive.
Gaming
Good for older games due to high clocks, but bottlenecks modern GPUs in CPU-heavy titles.
Slightly better than the 9100 due to cache and clocks, but 4 threads remain a hard bottleneck.
Virtualization
Limited by core count for running multiple VMs.
4 threads are insufficient for meaningful virtualization.
Efficiency
65W TDP offers a good balance of power and heat.
The 62 W TDP makes it slightly more efficient per clock than the 65 W 9100.
Specialized Performance
AI / ML
- No AI acceleration hardware
- Inadequate for local AI inference
- No AI capabilities
Content Creation
Gaming
- High single-core clocks help older games
- 4 threads cause stuttering in modern AAA titles
- Requires a discrete GPU for any real gaming
- Can handle very light esports at low settings if paired with a dedicated GPU
- The 4-thread limit causes significant stuttering in modern games

Our Verdict on Each
Offers the best single-thread performance of the locked 7th Gen i5s, but the 4-core/4-thread limitation makes it a poor choice for modern multi-threaded workloads.
Best for: Upgrading an older LGA 1151 system where maximum single-thread speed is needed without overclocking.
Read the full reviewThe i3-9300 is a minor tweak on the 9100, offering a bit more cache and slightly better efficiency, but its OEM-exclusive nature and 4-thread limit make it irrelevant for DIY builders.
Best for: The i3-9300 should only be considered if you are purchasing a pre-built desktop from an OEM (like HP or Lenovo) that happens to use this chip, and the price is heavily discounted. The 8 MB cache makes it a slightly better performer than a 9100 in single-task office environments. If you are building a PC yourself, you cannot buy this chip, and you shouldn't try to hunt it down on the grey market.
