AMD Ryzen 7 3800XT vs Intel Core i7-10875H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear overall picture: the AMD Ryzen 7 3800XT wins 9 of the 10 recorded head-to-head comparisons, while the Intel Core i7-10875H takes a single narrow victory. The margin of that Intel win is minimal. In the 3dmark single-thread test, the Intel scores 753 against the AMD's 748, a delta of just 0.7%. That is the only benchmark where the mobile Intel part leads, and the advantage is essentially negligible in practical terms.

The AMD part's biggest win comes in the Cinebench R15 multicore test. There, the Ryzen 7 3800XT scores 2230 against the Intel's 1233, a delta of 44.7%. That is an enormous gap, and it indicates that the desktop AMD processor sustains its multi-threaded workload performance far better than the mobile Intel chip. The Cinebench R15 single-core test also goes to AMD, with a score of 219 versus 174, a 20.5% advantage.

The pattern repeats across other workloads. In Geekbench multicore, the AMD scores 8561 versus 6511, a 23.9% delta. In Geekbench single-core, the AMD scores 1773 versus 1384, a 21.9% delta. The 3DMark suite shows consistent AMD wins at every thread count except the single-thread test. At 16 threads, AMD leads 6307 to 5104, a 19.1% delta. At max threads, AMD leads 6294 to 5081, a 19.3% delta. At 8 threads, AMD leads 4743 to 4050, a 14.6% delta. At 4 threads, AMD leads 2795 to 2527, a 9.6% delta. Even at 2 threads, AMD leads 1475 to 1404, a 4.8% delta.

The data suggests that the Ryzen 7 3800XT is faster in nearly every scenario measured, and often by a wide margin. The only exception is the 3dmark single-thread test, where the Intel part's boost clock of 5.10 GHz likely contributes to its slight edge. However, that single win does not offset the AMD part's dominance in the other nine tests.

Where Each One Wins

The AMD Ryzen 7 3800XT is the clear choice for multi-threaded and heavily parallel workloads. Its wins in Cinebench R15 multicore, Geekbench multicore, and all 3DMark multi-thread tests demonstrate strong scaling across 2, 4, 8, 16, and max thread counts. The 44.7% delta in Cinebench R15 multicore is the single largest performance gap in the dataset, suggesting that rendering, video encoding, and other CPU-intensive tasks would favor the AMD part substantially.

The Intel Core i7-10875H's only win is the 3dmark single-thread test, with a 0.7% delta. That margin is too small to be considered a meaningful advantage. In the other single-thread tests, Cinebench R15 single-core and Geekbench single-core, the AMD wins by 20.5% and 21.9% respectively. Thus, even for lightly threaded tasks, the AMD part generally holds the lead.

For users who require integrated graphics, the Intel part has UHD Graphics, while the AMD Ryzen 7 3800XT has no integrated graphics. That is a functional difference, not a performance one, and it matters for systems without a discrete GPU. For pure CPU performance, the data consistently favors the AMD processor.

Specification Differences

The two processors differ in several core specifications. The Intel Core i7-10875H has a base clock of 2.30 GHz and a boost clock of 5.10 GHz, while the AMD Ryzen 7 3800XT has a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The Intel part has a TDP of 45 watts, while the AMD part has a TDP of 105 watts.

The sockets are different: the Intel uses Intel BGA 1440, and the AMD uses AMD Socket AM4. The Intel part is a mobile processor, while the AMD part is a desktop processor. The Intel part includes integrated graphics (UHD Graphics), while the AMD part has none. The Intel part has a locked multiplier, while the AMD part has an unlocked multiplier.

The Intel Core i7-10875H is built on the Comet Lake architecture, specifically Comet Lake-H, using a 14 nm process node from Intel. The AMD Ryzen 7 3800XT is built on the Zen 2 architecture, codenamed Matisse 2, using a 7 nm process node from TSMC. The AMD part has 3,800 million transistors and a die size of 74 mm², while the Intel part has a die size of 177.5 mm² and no transistor count recorded.

Cache configurations differ notably. Both have 64 KB of L1 cache per core. The Intel part has 256 KB of L2 cache per core, while the AMD part has 512 KB of L2 cache per core. The Intel part has 16 MB of shared L3 cache, while the AMD part has 32 MB of L3 cache. Neither supports ECC memory. Neither has 3D V-Cache.

The Verdict

The data points to the AMD Ryzen 7 3800XT as the stronger performer in almost every benchmark category. It wins 9 of 10 head-to-head comparisons, with its largest win being a 44.7% delta in Cinebench R15 multicore. It also leads in single-core tests by roughly 20% in both Cinebench R15 and Geekbench. The only Intel win, the 3dmark single-thread test, is by a 0.7% margin, which is not enough to recommend the Intel part on performance grounds.

The Intel Core i7-10875H does have advantages in specific areas unrelated to raw benchmark scores. It is a mobile processor with a 45 watt TDP, which makes it suitable for laptops, and it includes integrated graphics. The AMD part is a desktop processor with a 105 watt TDP and no integrated graphics. Users building a desktop system without a discrete GPU would need to consider that the AMD part requires a separate graphics card.

The AMD part also offers more L3 cache, 32 MB versus 16 MB, and larger L2 cache per core, 512 KB versus 256 KB. It supports PCIe Gen 4 instead of Gen 3. Its unlocked multiplier allows overclocking, and its launch MSRP is $399, which is lower than the Intel part's launch MSRP of $450.

For users who need a mobile processor with integrated graphics, the Intel Core i7-10875H is the only option between these two, since the AMD part is desktop-only. For users building a desktop system and prioritizing CPU performance, the AMD Ryzen 7 3800XT is the stronger choice based on the recorded benchmark data. The 44.7% Cinebench R15 multicore gap and the 23.9% Geekbench multicore gap are decisive for multi-threaded workloads, and the AMD part also leads in single-core tests. The Intel part's single benchmark win is too narrow to change that conclusion.
