AMD A8-6600K vs Intel Celeron G5920 Comparison

Where Each One Wins

The two processors in this comparison occupy very different positions in the desktop landscape, and the data reflects that split clearly. The Intel Celeron G5920, built on the Comet Lake architecture with a 14 nm process, is a dual-core, two-thread part running at a fixed 3.50 GHz. Its benchmark results are concentrated in the Cinebench suite, where it posts a Cinebench R23 multi-core score of 2252 and a single-core score of 318. The AMD A8-6600K, in contrast, is a quad-core, four-thread Piledriver part from the Richland generation, built on a 32 nm process at GlobalFoundries. It runs at a base clock of 3.90 GHz and can boost up to 4.20 GHz, and its recorded data comes from the Geekbench suite: a multi-core score of 1076 and a single-core score of 451.

The Celeron G5920 wins where sustained multi-threaded rendering workloads are measured in the Cinebench family. Its Cinebench R15 multi-core score of 226, R20 multi-core score of 945, and R23 multi-core score of 2252 place it in a segment where the processor can handle light to moderate productivity tasks. The A8-6600K has no Cinebench results recorded in the database, so the direct comparison across that suite is not possible. Instead, the A8-6600K's wins appear in the Geekbench tests, where its quad-core configuration and higher clock speeds drive a multi-core score of 1076 and a single-core score of 451. The Celeron G5920 has no Geekbench results in the database, so again, the direct head-to-head across that suite is not possible.

The percentile rankings show the two are nearly level in overall standing. The Celeron G5920 sits at the 21st percentile of all CPUs, while the A8-6600K sits at the 20th percentile. Their average benchmark scores are close as well: the Celeron G5920 averages 775, and the A8-6600K averages 764. The nearest rivals for the Celeron G5920 include the Intel Core i3-3250T (average 775, delta 0%), the Intel Pentium Silver J5005 (average 776, delta -0.1%), the AMD Athlon X4 760K (average 777, delta -0.2%), and the Intel Core i7-3687U (average 773, delta 0.3%). For the A8-6600K, the nearest rivals are the Intel Core i7-3537U (average 766, delta -0.3%), the Intel Core i3-3240 (average 761, delta 0.5%), the Intel Core i5-3210M (average 758, delta 0.8%), and the Intel Core i3-5020U (average 757, delta 0.9%).

The practical takeaway is that the Celeron G5920 is the better choice for modern rendering benchmarks, while the A8-6600K holds its own in legacy Geekbench workloads. The A8-6600K's four physical cores give it an edge in parallel tasks that scale across threads, but the Celeron G5920's newer architecture and higher per-core efficiency show up in its Cinebench scores, which are more representative of current software.

The Verdict

The data points to a clear split based on workload and platform. For users who prioritize modern multi-threaded rendering performance, the Intel Celeron G5920 is the stronger pick. Its Cinebench R23 multi-core score of 2252 is a solid result for a dual-core part, and its average benchmark score of 775 edges out the A8-6600K's 764. The Celeron G5920 also benefits from being on the Intel Socket 1200 platform with DDR4 memory support and PCIe Gen 3 with 16 lanes, which are more current standards than the AMD Socket FM2 and DDR3 memory of the A8-6600K.

For users who need a processor with a higher clock speed and more physical cores, the AMD A8-6600K offers a different set of strengths. Its base clock of 3.90 GHz and boost clock of 4.20 GHz are well above the Celeron G5920's fixed 3.50 GHz. The quad-core configuration gives it an advantage in tasks that can use all four threads, and its Geekbench multi-core score of 1076 reflects that. However, the A8-6600K is end-of-life, runs on a 32 nm process, and consumes a 100 W TDP, which is significantly higher than the Celeron G5920's 58 W TDP.

The verdict from the recorded data is straightforward: the Celeron G5920 is the better all-around processor for modern workloads, with a higher average benchmark score, a more efficient process node, and a newer platform. The A8-6600K is a capable part for legacy systems, especially where the unlocked multiplier and higher clocks matter, but its performance in the database is lower overall. The Celeron G5920 should be the default recommendation for a new build, while the A8-6600K is only worth considering if the platform or specific Geekbench performance is a requirement.

Head-to-Head Benchmarks

Because the two processors were tested with different benchmark suites, the head-to-head comparison relies on the average benchmark score and the percentile rankings rather than direct test-by-test results. The Celeron G5920's average benchmark score of 775 is 1.4% higher than the A8-6600K's 764. That is a narrow margin, but it appears consistently across their respective suites.

The Celeron G5920's strongest recorded result is its Cinebench R23 multi-core score of 2252. That score places it in a range where it can handle multi-threaded rendering tasks that would be beyond the A8-6600K, had the A8-6600K been tested in that suite. The Celeron G5920 also posts a Cinebench R20 multi-core score of 945 and a Cinebench R15 multi-core score of 226, all of which indicate a processor that scales reasonably well for a dual-core part.

The A8-6600K's strongest recorded result is its Geekbench multi-core score of 1076, which reflects its four physical cores. Its single-core score of 451 is also notable, given that it runs at a base clock of 3.90 GHz with a boost up to 4.20 GHz. The A8-6600K's nearest rival, the Intel Core i7-3537U, has an average score of 766, which is 0.3% lower than the A8-6600K's 764, meaning the A8-6600K sits just above that rival in the database.

The percentile rankings reinforce the closeness of the two parts. The Celeron G5920 is at the 21st percentile, and the A8-6600K is at the 20th percentile. That one-percentile difference is within the noise of the database, and the average scores are separated by only 11 points. The biggest wins for each come from the specific workloads they were tested in: the Celeron G5920 wins in Cinebench rendering, and the A8-6600K wins in Geekbench general-purpose tests.

Architecture Differences

The two processors come from different architectural eras and foundries. The Intel Celeron G5920 is built on the Comet Lake architecture, a 14 nm process at Intel, and belongs to the Celeron generation. It uses a dual-core, dual-thread layout with a fixed 3.50 GHz clock. Its cache structure is 64 KB of L1 per core, 256 KB of L2 per core, and 2 MB of shared L3 cache. The memory support is DDR4 over a dual-channel bus, with a memory bandwidth of 42.7 GB/s. The processor uses PCIe Gen 3 with 16 lanes from the CPU, and its integrated graphics are the UHD 610. It is not multiplier unlocked, and its socket is Intel Socket 1200.

The AMD A8-6600K is built on the Piledriver architecture, specifically the Richland codename, using a 32 nm process at GlobalFoundries. It has 1,303 million transistors on a 246 mm² die, which is a larger and older process node than the Intel part. The A8-6600K has 4 cores and 4 threads, with a base clock of 3.90 GHz and a boost clock of 4.20 GHz. Its cache is 192 KB of L1 and 4 MB of L2, with no L3 cache listed. The memory support is DDR3 over a dual-channel bus, with a memory bandwidth of 29.9 GB/s. It uses PCIe Gen 2, and its integrated graphics are the Radeon HD 8570D. The multiplier is unlocked, and it uses the AMD Socket FM2.

The process node difference is significant: 14 nm for the Celeron G5920 versus 32 nm for the A8-6600K, which explains the large TDP gap of 58 W versus 100 W. The Celeron G5920 also has a newer socket and memory standard, which makes it more compatible with current motherboards and DDR4 RAM. The A8-6600K, with its four cores and higher clocks, was designed for a different era, and its lack of L3 cache is notable compared to the Celeron G5920's 2 MB of shared L3. The integrated graphics also differ, with the UHD 610 on the Intel side and the Radeon HD 8570D on the AMD side. These architectural differences explain why the two processors, despite similar average scores, serve different use cases.
