Intel Core i7 8th‑Gen Review: Specs and Performance
The 8th‑generation Intel Core i7 processors arrived at a time when competition from AMD’s Ryzen line was heating up, promising higher core counts without sacrificing the familiar single‑thread strength that many Windows users rely on. In this review we’ll break down the most common i7‑8700K and i7‑8700 models, walk through their specifications, and see how they stack up in synthetic benchmarks as well as everyday tasks.
Key Specifications at a Glance
- Architecture: Coffee Lake (14 nm)
- Core/Thread Count: 6 cores / 12 threads (i7‑8700) or 6 cores / 12 threads with higher boost (i7‑8700K)
- Base Clock: 3.2 GHz (i7‑8700) – 3.7 GHz (i7‑8700K)
- Turbo Boost: Up to 4.6 GHz (i7‑8700) – up to 4.7 GHz (i7‑8700K)
- Cache: 12 MB Smart Cache
- TDP: 65 W (i7‑8700) – 95 W (i7‑8700K)
- Integrated Graphics: Intel UHD Graphics 630
These numbers signal a clear shift from the previous 6‑core 4‑thread 7th‑gen chips, delivering more parallelism for multi‑threaded workloads while keeping the high clock speeds that benefit gaming.
Benchmark Performance
When put through popular suites like Cinebench R20 and Geekbench 5, the i7‑8700K typically posts around 1,250 points in the multi‑core test—about 20 % faster than its 7th‑gen predecessor. Single‑core scores hover near 1,300, which remains competitive for most titles that still lean heavily on a single thread.
In gaming, the difference is subtler. At 1080p with a mid‑range GPU, the i7‑8700K can shave roughly 5–7 FPS compared to a non‑K sibling, but the gap narrows dramatically when the graphics card becomes the bottleneck. In CPU‑intensive games such as Shadow of the Tomb Raider or Assassin’s Creed Valhalla, the extra boost clock can translate to a smoother experience, especially when paired with high refresh‑rate monitors.
Real‑World Usage: From Content Creation to Everyday Tasks
For video editors working with 1080p or even 4K footage, the six cores and twelve threads provide a noticeable lift when rendering in Adobe Premiere Pro or DaVinci Resolve. Render times drop by roughly 15–20 % compared to a similarly priced i5‑8600K.
Programmers and data analysts will appreciate the larger cache and improved hyper‑threading. Multithreaded compilation of large codebases, such as the Linux kernel, finishes noticeably quicker. On the flip side, casual users who browse the web, stream videos, or run office apps will see only marginal gains over a solid i5, as those tasks rarely tap the extra threads.
Power Consumption and Thermals
The non‑K i7‑8700, with its 65 W TDP, fits nicely into standard mid‑tower builds without demanding exotic cooling solutions. The K‑variant, however, pushes the envelope: under heavy load it can draw close to 150 W, and temperatures can climb past 80 °C if the cooler isn’t up to the task. Many reviewers recommend a quality air cooler with a 150 mm fan or an AIO liquid cooler for sustained turbo performance.
Strengths and Weaknesses
Strengths:
- Six cores strike a sweet spot for both gaming and productivity.
- High boost clocks keep single‑thread performance competitive.
- Compatible with existing 300‑series motherboards (with a BIOS update).
- Reasonable price‑to‑performance ratio when AMD alternatives were still catching up.
Weaknesses:
- Still built on a 14 nm process, lagging behind AMD’s 7 nm efficiencies.
- Thermal demands of the K‑models require better cooling.
- Limited overclocking headroom compared to later generations.
Who Should Consider the 8th‑Gen i7?
If you’re assembling a PC in 2024 and already own a compatible 300‑series motherboard, the i7‑8700K can be a cost‑effective upgrade for a gaming rig that also does light video editing. For builders who prioritize future‑proofing, newer 12th‑ or 13th‑gen CPUs may offer more cores and better efficiency, but they also demand newer chipsets and DDR5 memory.
In short, the 8th‑gen i7 remains a solid middle ground: powerful enough for most current games, capable for creative workloads, and affordable on the secondhand market.
Frequently Asked Questions
Is the i7‑8700K still worth buying for a new gaming PC?
It can be, especially if you find a good deal and already have a compatible motherboard. The CPU will handle modern titles at 1080p or 1440p without bottlenecking a mid‑range GPU, though you won’t get the absolute top performance of the latest Intel or AMD releases.
Can the i7‑8700K be overclocked safely?
Yes, but you’ll need a robust cooling solution and a quality motherboard with a solid power delivery design. Expect modest overclocks—pushing the boost clock into the 5.0 GHz range is feasible, though thermal limits will quickly become the limiting factor.
How does the i7‑8700 compare to AMD’s Ryzen 5 2600?
Both have six cores and twelve threads, but the i7‑8700 typically wins in single‑core tests by about 10 % and edges out in multi‑core performance thanks to higher clock speeds. Power consumption, however, is generally lower on the Ryzen 5 2600.
Will the integrated UHD Graphics 630 suffice for casual gaming?
The UHD 630 can handle older or indie titles at low settings, but for anything beyond that you’ll want a discrete GPU. It’s mainly useful as a backup display output.
