8th Gen Intel Core i7-8700K Review
The 8th Gen Intel Core i7-8700K is an unlocked 6-core, 12-thread desktop processor built on Coffee Lake, running a 3.7 GHz base clock that boosts to 4.7 GHz within a 95 Watt TDP on the LGA 1151 socket.
This chip was a genuine milestone for Intel's mainstream desktop lineup, marking the jump from 4-core to 6-core i7 chips and remaining a popular enthusiast overclocking choice years after launch.
Intel UHD Graphics 630
A basic integrated GPU intended for display output; enthusiast desktop builds around this chip typically pair it with a discrete GPU.
How Is the Core i7-8700K in Terms of Performance
The unlocked multiplier and genuinely strong 4.7 GHz boost clock made this chip a favorite among enthusiast overclockers at launch, with the jump to 6 cores representing a real generational leap over the previous 4-core i7 lineup.
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
- 8th Gen Intel Core i7-8700K (this product)5124.75 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
- 8th Gen Intel Core i7-8700K (this product)5629.43 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
- 8th Gen Intel Core i7-8700K (this product)4410.6 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.
Puget Bench for Premiere Pro v2.0 - points (More is Better)
- Apple M5 Max149750.46 points
- Intel Core i9-14900KF129174.45 points
- AMD Ryzen 7 9800X3D126611.82 points

- 10th Gen Intel Core i9 10850K78258 points

Puget Bench for Lightroom Classic v1.0-1.1 - points (More is Better)
- Apple M5 Max11549.6 points
- AMD Ryzen 7 9800X3D10942.9 points
- Apple M5 Pro10909.17 points
- Apple M56668.19 points

- 11th Gen Intel Core i5 11600KF5499.67 points
- 8th Gen Intel Core i7-8700K (this product)4175.75 points
Measures a full Lightroom Classic catalogue workflow: importing, building previews, scrolling the library, exporting JPEGs and running the AI tools such as Denoise.
Import and export spread across every core, so core count counts for more here than it does in Photoshop. The AI tools lean on the graphics card, so a CPU gap matters less if you pair either chip with a strong GPU.
Benchmarks
Cinebench R20 single-core scores of 470 reflect genuinely strong per-core performance for its generation, a key reason this chip remained popular for gaming builds years after its original launch.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- Enthusiast desktop builders wanting an unlocked, overclockable 6-core chip with genuinely strong per-core performance
Not for
- Buyers wanting the latest architecture, considerably newer chips offer meaningful IPC and efficiency improvements
