AMD Ryzen 7 9800X3D vs Intel Core 7 251E Comparison

The AMD Ryzen 7 9800X3D and Intel Core 7 251E occupy different positions in the database. The AMD is an 8-core, 16-thread Zen 5 desktop part with a 96 MB shared L3 cache, a 4.70 GHz base clock, and recorded scores across 3DMark, Cinebench, Geekbench, and Passmark. The Intel is a 24-core, 32-thread Bartlett Lake desktop part with a 36 MB shared L3 cache, a 2.10 GHz base clock, and no recorded benchmark entries. The database therefore offers a measured side and a specification-only side.

Where Each One Wins

The database records 0 direct head-to-head benchmark wins for either processor. In the absence of direct comparisons, the AMD accumulates every measured win because it is the only CPU in this comparison with benchmark rows. Its 3DMark scores run from 1212 in the single-thread test to 10081 in the 16-thread test, with 10067 in max-thread. Cinebench R23 scores are 2080 single-core and 23230 multi-core. Geekbench scores are 2964 single-core and 18696 multi-core. Passmark results include 4430 single-thread, 40009 multi-thread, 116709 integer math, 79456 floating point math, 38808 extended instructions, 468017 data compression, 22158 data encryption, 48526 random string sorting, 4083 physics, and 423 find prime numbers. The Intel part has none of these entries, so the AMD is the only processor in this comparison with recorded benchmark wins.

The Intel side wins on specification comparisons. It has 24 cores and 32 threads versus 8 cores and 16 threads. Its boost clock is 5.60 GHz versus 5.20 GHz. Its TDP is 65 W versus 120 W. It supports DDR4 and DDR5, while the AMD supports DDR5 only. Its integrated graphics are UHD Graphics 770, while the AMD uses Radeon Graphics. The AMD counters with a 4.70 GHz base clock versus 2.10 GHz, a 96 MB L3 cache versus 36 MB, 24 PCIe Gen 5 lanes versus 16, an unlocked multiplier versus a locked one, and an 87th percentile versus 50th.

Head-to-Head Benchmarks

The head-to-head benchmark table for this pair is empty. The database records 0 direct benchmark runs and 0 wins for either processor. As a result, the largest measurable wins belong to the AMD by default: it has scores in 3DMark, Cinebench, Geekbench, and Passmark, while the Intel has none.

Within the AMD's recorded results, the largest multi-thread scores are Cinebench R23 multi-core at 23230, Geekbench multi-core at 18696, Passmark multi-thread at 40009, and 3DMark 16-thread at 10081. The largest single-thread scores are Passmark single-thread at 4430, Geekbench single-core at 2964, Cinebench R23 single-core at 2080, and 3DMark single-thread at 1212.

Against the four closest database entries, the AMD's average score of 39768 sits in a tight cluster. The Ryzen 7 7700 leads by 0.8%, the Ryzen AI 9 365 leads by 0.7%, the Ryzen 7 PRO 8840HS trails by 0.4%, and the Ryzen AI 7 450 trails by 0.7%. The AMD's measured average is therefore within a 0.8% band of all four comparables, neither a clear leader nor a laggard among them.

The Intel's specification sheet lists 24 cores and a 5.60 GHz boost clock, but the database provides no measured score for the Intel, so no performance conclusion can be drawn from measurements.

Specification Differences

The table below lists the fields where the two processors differ in the database. Fields that match, such as dual-channel memory, 89.6 GB/s bandwidth, ECC support, the desktop market segment, and active production status, are omitted.

Architecture Differences

The architecture records separate the two parts clearly. The AMD uses the Zen 5 architecture with the Granite Ridge codename, produced on a 4 nm TSMC process with 8,315 million transistors on a 70.6 mm² die. The Intel uses the Bartlett Lake codename, with no architecture name recorded in the database, produced on a 10 nm Intel process with a 257 mm² die and no transistor count recorded.

Both parts use 80 KB of L1 cache per core. The AMD uses 1 MB of L2 per core and 96 MB of shared L3; the Intel uses 2 MB of L2 per core and 36 MB of shared L3. The AMD integrates Radeon Graphics; the Intel integrates UHD Graphics 770. The AMD exposes 24 PCIe Gen 5 lanes from the CPU; the Intel exposes 16. The AMD supports DDR5 only; the Intel supports DDR4 and DDR5. The AMD multiplier is unlocked; the Intel multiplier is locked.

Both parts are desktop processors with active production status, dual-channel memory, 89.6 GB/s memory bandwidth, and ECC support.

The Verdict

The data supports a split verdict. On measured performance, the AMD Ryzen 7 9800X3D is the only processor of the two with recorded benchmark scores. Its 87th percentile and average score of 39768 place it within 0.8% of the Ryzen 7 7700 and the Ryzen AI 9 365, and ahead of the Ryzen 7 PRO 8840HS and the Ryzen AI 7 450 by 0.4% and 0.7%, respectively. The Intel Core 7 251E has no recorded scores, so no measured comparison is possible.

On specifications, the Intel wins on core count (24 versus 8), thread count (32 versus 16), boost clock (5.60 GHz versus 5.20 GHz), TDP (65 W versus 120 W), and memory compatibility (DDR4 and DDR5 versus DDR5). The AMD wins on base clock (4.70 GHz versus 2.10 GHz), L3 cache (96 MB versus 36 MB), PCIe Gen 5 lanes (24 versus 16), an unlocked multiplier, and the presence of recorded benchmark data.

The database's verdict: the AMD is the part with measured results and the larger cache; the Intel is the part with more cores, a lower power envelope, and broader memory support. A build that relies on recorded benchmark data points to the AMD; a build that prioritizes core count, power, and memory flexibility points to the Intel.
