10th Gen Intel Core i5 10400 Review
The 10th Gen Intel Core i5 10400 is a 6-core, 12-thread desktop processor for the LGA 1200 socket, with a 2.9 GHz base clock, 4.3 GHz boost, 12 MB L3 cache and a 65 W TDP.
A mainstream Comet Lake processor with Intel UHD Graphics 630, so it can drive a display without a graphics card. Memory support is DDR4-2666, and PCIe 3.0 with 16 lanes. The launch price was $182 in 2020. The socket status is listed as end of life, so this is a budget or replacement choice, not a new platform. Six cores and 12 threads still handle everyday computing, office work and mainstream gaming with a separate graphics card. It does not support ECC memory and is built on a 14 nm process.
Integrated Graphics
The standard non-F variant of this chip includes Intel UHD Graphics 630 for basic display output; buyers should confirm the specific SKU (10400 vs. 10400F) before assuming integrated graphics availability.
How Is the Core i5 10400 in Terms of Performance
The 6-core, 12-thread layout gives this chip genuinely solid mainstream desktop performance for gaming and everyday productivity, positioned as a budget-friendly alternative to unlocked K-series chips for buyers who don't plan to overclock.
Benchmarks
The benchmarks below are published results for specific applications. They are measured separately and do not feed the two scores above.
Puget Bench for Photoshop v1.0 - points (More is Better)
- Apple M5 Max15043.83 points
- Apple M5 Pro14885.21 points
- Apple M512095.89 points
- AMD Ryzen 7 9800X3D12088.31 points
- Intel Core i9-14900KF10029.96 points
- 11th Gen Intel Core i7 11700K7098.88 points
- 10th Gen Intel Core i9-10900KF6892.97 points
- 10th Gen Intel Core i5 10400 (this product)4855.64 points
Puget Systems runs a fixed set of real Photoshop jobs: opening and saving large files, resizing, content-aware fill, blurs and filters. A higher score means less waiting on the tasks a retoucher repeats all day.
Photoshop is decided mostly by how fast a few cores are, not how many there are, so a chip with fewer but faster cores often beats one with more cores. Treat a gap under about 5 percent as something you would never notice while working.
Puget Bench for Premiere Pro v1.0-1.1 - points (More is Better)
- 10th Gen Intel Core i9-10900KF8213.67 points
- 11th Gen Intel Core i7 11700K8123.47 points
- 10th Gen Intel Core i9 10920X8063.5 points
- 10th Gen Intel Core i9 10900K7881.73 points
- 10th Gen Intel Core i9-10980XE7835.06 points
- 10th Gen Intel Core i9 10850K7227.4 points
- 9th Gen Intel Core i9-9900KS7211.33 points
- 10th Gen Intel Core i5 10400 (this product)4786.67 points
Plays back and exports 4K and 8K timelines across several camera codecs, with effects and multi-stream sequences, in Adobe Premiere Pro.
Export time rewards more cores, but much of the timeline work runs on the hardware decoder and the graphics card instead of the processor. A small gap here rarely changes how the edit feels.
Puget Bench for DaVinci Resolve v1.0-1.2 - points (More is Better)
- 10th Gen Intel Core i9 10900K7805.2 points
- 10th Gen Intel Core i9-10980XE7088 points
- 10th Gen Intel Core i9 109006352 points
- 10th Gen Intel Core i9 10850K6101.6 points
- 11th Gen Intel Core i7 11700K6038.67 points
- 10th Gen Intel Core i9 10920X5853.67 points
- 9th Gen Intel Core i9-9900K5670.25 points
- 10th Gen Intel Core i5 10400 (this product)4545.5 points
Grading, effects, AI tools and export in DaVinci Resolve Studio, across the codecs a colourist actually works in.
Resolve leans harder on the graphics card than on the processor, so the CPU difference here is usually smaller than the difference your GPU choice would make. Use it to rule out a bottleneck, not to pick a winner.
Benchmarks
This chip's close sibling, the i5-10400F, posted Cinebench R23 multi-core scores of 7,617 and single-core scores of 1,111 in testing, providing a useful reference point for the shared 6-core Comet Lake architecture the standard 10400 also uses.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- Budget-conscious desktop builders wanting solid mainstream 6-core performance without paying for overclocking headroom
Not for
- Enthusiasts wanting to overclock, the unlocked i5-10600K or Rocket Lake i5-11600K offer that flexibility
