Intel Core i7-8700B

The Intel Core i7-8700B is a Coffee Lake processor from Intel built on the 14 nm process. It has 6 cores and 12 threads, with a base clock of 3.20 GHz and a boost clock of 4.60 GHz. The part is listed in the desktop market segment, uses the Intel BGA 1440 socket, and carries a 65 W TDP. Its benchmark data shows an average score of 3077 and a 55th percentile position among all CPUs in the database. The chip was released on 2018-04-02 and is now end-of-life. It includes 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 12 MB of shared L3 cache, with dual-channel DDR4 memory support at 42.7 GB/s.

How It Compares

The closest rival in aggregate score is the AMD Ryzen 3 PRO 7330U. That part averages 3063, while the i7-8700B averages 3077. The delta is 0.4%, placing the two effectively in the same performance band.

The Intel Xeon E5-1660 v3 sits slightly higher with an average score of 3092. The i7-8700B trails that result by 0.5%, a narrow margin that keeps the comparison close.

The Intel Core i7-11375H averages 3058, which is 0.6% lower than the i7-8700B. The 8700B holds a small but consistent edge over this rival.

The largest gap in the nearest-rival group belongs to the Intel Xeon W-2133, with an average score of 3107. The i7-8700B is 1% behind that score, still a tight margin. Taken together, all four listed rivals sit within 1% of the i7-8700B, so the chip occupies a tightly clustered performance position rather than a clear leadership or trailing role.

Who Should Consider It

Users running single-thread-sensitive workloads will find the relevant signals in the single-core benchmark scores. The i7-8700B scores 1415 in Cinebench R23 single-core and 1482 in Geekbench single-core. These scores point to responsive behavior for office applications, document editing, and other interactive tasks that depend on low-latency single-thread execution.

For content creation and rendering workloads, the multi-core results are the important numbers. The Cinebench R20 multi-core score is 4211, and the R23 multi-core score is 10027. These indicate that the 6-core, 12-thread configuration can carry parallel workloads such as rendering, encoding, and compilation. Users who regularly run fully threaded applications should weigh these scores more heavily than the single-core measurements.

For gaming, the data contains no GPU benchmark, so the CPU-side view comes from the single-thread results. The R15 single-core score of 142 and R20 single-core score of 594 show a moderate single-thread footprint. The integrated UHD Graphics 630 provides display output without a discrete GPU, but the benchmark set does not include a graphics performance test.

The i7-8700B is also a fit for general productivity systems that benefit from 12 threads plus integrated graphics. The dual-channel DDR4 support and 42.7 GB/s memory bandwidth cover light multitasking and everyday memory traffic. Users looking for an overclockable part should look elsewhere, because the multiplier is locked.

Benchmark Performance

The aggregate benchmark score of 3077 places the i7-8700B near the middle of the database distribution. Against its nearest rivals, the deltas are small: 0.4% higher than the AMD Ryzen 3 PRO 7330U, 0.6% higher than the Intel Core i7-11375H, 0.5% lower than the Intel Xeon E5-1660 v3, and 1% lower than the Intel Xeon W-2133.

Across individual tests, the results follow a consistent pattern. In Cinebench R15, the multi-core score is 1010 and the single-core score is 142. In Cinebench R20, the multi-core score is 4211 and the single-core score is 594. In Cinebench R23, the multi-core score is 10027 and the single-core score is 1415. Geekbench reports a multi-core score of 5736 and a single-core score of 1482.

These numbers show that the multi-core result is substantially larger than the single-core result in every benchmark generation. That pattern is expected for a 6-core, 12-thread processor. The 55th percentile position reinforces the idea that this CPU sits in the middle of the overall field, with no listed rival more than 1% away in average score.

FAQ

A: It includes Intel UHD Graphics 630.

Q: What is the L3 cache capacity?

A: It has 12 MB of shared L3 cache.

Q: What was the launch MSRP?

A: The launch MSRP was $303.

Power and Thermals

Power behavior is defined by the 65 W TDP. This is a moderate thermal envelope for a 6-core, 12-thread CPU built on the 14 nm process. The die size is 154 mm², which provides another physical reference point for the package.

For cooling, the 65 W TDP implies a conventional air cooler is within the expected tier. Nothing in the supplied data suggests that a high-end liquid cooling loop is necessary. Because the multiplier is locked, there is no default overclocking path, so cooling does not need to account for raised clocks or extra voltage. The BGA 1440 socket also means the cooling solution must match a board-mounted package rather than a socketed desktop CPU.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance dominates the benchmark profile. In Cinebench R15, the single-core score is 142 and the multi-core score is 1010. In R20, the single-core score is 594 and the multi-core score is 4211. In R23, the single-core score is 1415 and the multi-core score is 10027. Geekbench reports 1482 single-core and 5736 multi-core.

In every test, the multi-core result is far larger than the single-core result. This is the expected signature of a processor with 6 cores and 12 threads. Workloads that can spread work across all threads should approach the higher multi-core scores, while workloads that are limited to one thread will land near the single-core numbers.

The practical implication is that the i7-8700B shows its strength in parallel work. Lightly threaded tasks will rely on the lower single-core scores, which are still moderate but not exceptional. The data does not include single-thread scores for the nearest rivals, so the within-chip comparison is the clearest signal available: the multi-thread advantage is large, and that is what separates the CPU’s behavior across different application types.
