CPU Comparison
Intel Core i5-8500T vs Intel Core i5-4590T
A side-by-side comparison of specs, performance and value. The Intel Core i5-8500T is a low-power desktop processor from the 8th generation Coffee Lake family. Released in April 2018, it is built on the 14nm process and features 6 cores and 6 threads. The 'T' suffix indicates a 35W TDP, making it ideal for small form factor PCs, AIOs, and office environments. The base clock is 2.1 GHz, with a maximum turbo boost of 3.5 GHz, offering a good balance between power efficiency and performance. It includes 9 MB of Intel Smart Cache and supports dual-channel DDR4 memory up to 2666 MT/s. The integrated Intel UHD Graphics 630 provides basic display capabilities. With 16 PCIe 3.0 lanes, it offers adequate expansion for a discrete GPU and NVMe storage. Compatible with LGA 1151 motherboards on 300-series chipsets, the i5-8500T is a step up from the 8400T, providing higher clock speeds for users needing more responsiveness in a compact footprint.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
6 cores handle office tasks easily, with decent single-core speed.
Adequate for basic office tasks where bursty workloads benefit from the 3.0 GHz turbo, but sustained multi-threaded work is limited.
Gaming
Can handle light games, but low clocks limit high-refresh gaming.
The 2.0 GHz base clock severely limits gaming performance. Only viable for very old or casual games, even with a dedicated GPU.
Virtualization
Good for 1-2 VMs, but lacks hyper-threading.
Four threads at low clocks make virtualization impractical for any meaningful workload.
Efficiency
Outstanding efficiency with a 35W TDP.
The 35W TDP was impressive for a quad-core in 2014, though modern processors achieve far better performance at similar or lower power.
Specialized Performance
AI / ML
- No dedicated AI hardware.
- Low clocks make inference slow.
- No AI acceleration hardware
- Low clock speeds further reduce any AVX2 compute capability
- 35W power budget leaves no headroom for inference workloads
- Not viable for any AI application
Content Creation
Gaming
- Clocks are too low for modern CPU-bound games.
- UHD 630 is only good for very light titles.
- Needs a low-end discrete GPU for decent gaming.
- 2.0 GHz base clock too low for consistent game performance
- 3.0 GHz turbo helps in short bursts but cannot sustain
- Only suitable for pre-2015 games at low settings
- HD 4600 insufficient for any modern gaming without a dGPU
- Even with a dGPU, CPU bottleneck is severe in modern titles

Our Verdict on Each
An excellent low-power 6-core processor that offers better performance than the 8400T, making it a great choice for SFF builds where space and power are constrained.
Best for: Building a quiet home server or SFF office PC using used parts.
Read the full reviewAn impressive engineering exercise in power efficiency that sacrificed significant performance for its 35W TDP. Ideal for thermally constrained builds of its era, but modern low-power CPUs deliver far better performance at similar power envelopes.
Best for: Replacing a failed CPU in an existing thin mini-ITX or all-in-one system that requires a 35W LGA 1150 processor
