Intel Celeron G5920 vs Intel Core i7-3687U Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably tight contest between the Intel Celeron G5920 and the Intel Core i7-3687U. Across all five shared Cinebench workloads, the Celeron G5920 claims victory in every single test, yet the margin is consistently narrow, never exceeding 1%. This is not a case of one chip dominating; rather, it is a story of a desktop part edging out a mobile part by a hair in every measurable scenario.

In Cinebench R15 multicore, the Celeron G5920 scores 226 against the i7-3687U's 224, a delta of 0.9%. The R20 multicore test shows a similar pattern: 945 versus 937, again a 0.9% gap in favor of the Celeron. Moving to single-core workloads, the results are even closer. In Cinebench R20 single-core, the Celeron posts 133 while the i7-3687U posts 132, a mere 0.8% difference. The R23 suite follows suit: multicore is 2252 against 2231 (0.9% delta), and single core is 318 against 315 (1% delta). The largest advantage the Celeron manages is that 1% lead in R23 single-core, which is statistically negligible.

The average benchmark score in the database puts the Celeron G5920 at 775 and the i7-3687U at 773. This places the two parts within 0.3% of each other, with the Celeron holding a fractional edge. The percentile ranking for both is identical at the 21st percentile among all CPUs, confirming that they occupy the same performance tier. The head-to-head record is 5 wins for the Celeron and 0 for the i7-3687U, but those wins are all by less than a single percentage point.

The i7-3687U does have one benchmark in the database that the Celeron lacks: Geekbench. In that suite, the i7-3687U scores 1044 in multicore and 526 in single-core. Since the Celeron has no recorded Geekbench score, this cannot be compared directly, but it does show the i7-3687U's capability in a different rendering engine.

FAQ

Q: Which CPU has the higher average benchmark score?

A: The Intel Celeron G5920 records an average benchmark score of 775, while the Intel Core i7-3687U records 773, a difference of 0.3% in the Celeron's favor.

Q: How many benchmark wins does each CPU have in the head-to-head tests?

A: The Celeron G5920 wins all five recorded head-to-head tests. The i7-3687U wins zero. However, each win is by a delta of 0.8% to 1%, making the overall performance essentially equivalent.

Q: What is the single-core performance difference in Cinebench R23?

A: The Celeron G5920 scores 318 in Cinebench R23 single-core, while the i7-3687U scores 315. This gives the Celeron a 1% advantage, the largest margin of any head-to-head test.

Q: Which CPU has a higher power limit?

A: The Intel Celeron G5920 has a TDP of 58 watts, while the Intel Core i7-3687U has a TDP of 17 watts. The i7-3687U is designed for lower power consumption, typical of a mobile processor.

Q: Do both CPUs have the same number of threads?

A: No. The Celeron G5920 has 2 threads, while the i7-3687U has 4 threads. The i7-3687U supports Hyper-Threading, but this does not translate into a performance advantage in the recorded Cinebench results.

Q: What is the release date difference between the two?

A: The Intel Core i7-3687U was released on 2013-01-07, while the Intel Celeron G5920 was released on 2020-04-29. The Celeron is over seven years newer.

The Verdict

The data indicates that for raw compute performance, there is no meaningful winner. The Celeron G5920 edges out the i7-3687U in every Cinebench benchmark, but the margins are all under 1%. The average benchmark scores (775 vs. 773) and identical 21st percentile rankings reinforce that these two processors deliver essentially the same level of output in the recorded tests.

The choice between them must be based on factors other than performance. The i7-3687U is a mobile part with a 17 watt TDP, making it suitable for power-constrained environments. The Celeron G5920 is a desktop part with a 58 watt TDP, which will require more substantial cooling and power delivery. The i7-3687U also has a boost clock up to 3.30 GHz, while the Celeron is locked at 3.50 GHz base with no boost capability.

For a user prioritizing low power consumption and a compact mobile form factor, the i7-3687U is the logical choice despite being the older part. For a user building a desktop system who wants the slight edge in Cinebench scores, the Celeron G5920 offers that advantage, albeit small. The i7-3687U has a larger L3 cache (4 MB vs 2 MB) and more threads, but the benchmark results show these features do not translate into higher scores in the recorded workloads.

Architecture Differences

The two CPUs come from entirely different eras of Intel's design. The Intel Celeron G5920 is based on the Comet Lake architecture, built on a 14 nm process node. It is a desktop part for the Intel Socket 1200 platform. The processor has 2 cores and 2 threads, with L1 and L2 caches of 64 KB and 256 KB per core, respectively. The L3 cache is 2 MB shared. It supports DDR4 memory in a dual-channel configuration with a bandwidth of 42.7 GB/s. It also features PCIe Gen 3 with 16 lanes. The integrated graphics are UHD 610.

The Intel Core i7-3687U is based on the much older Ivy Bridge architecture, built on a 22 nm process node. It is a mobile part, socketed in Intel BGA 1023. It has 2 cores and 4 threads, with the same L1 (64 KB per core) and L2 (256 KB per core) caches. However, its L3 cache is doubled to 4 MB shared. It supports DDR3 memory in dual-channel mode, and its memory bandwidth is not listed in the database. No PCIe information is provided. Its integrated graphics are Intel HD 4000.

The die size for the i7-3687U is recorded as 118 mm², while the Celeron's die size is not listed. The i7-3687U also has a boost clock of 3.30 GHz, while the Celeron G5920 has no boost clock at all. The architecture differences explain the TDP gap: the 14 nm Comet Lake part consumes 58 watts, while the 22 nm Ivy Bridge part consumes only 17 watts. The i7-3687U is clearly optimized for a mobile environment, while the Celeron G5920 is a desktop budget part. Despite the architectural gap of seven years and a different process node, the benchmark data shows they deliver nearly identical results in the tested Cinebench workloads. The i7-3687U's extra threads and larger cache do not compensate for its lower base clock and older design in these specific tests.
