AMD Ryzen 9 9900X vs Intel Core 7 251TE Comparison

# AMD Ryzen 9 9900X vs Intel Core 7 251TE

The AMD Ryzen 9 9900X and Intel Core 7 251TE occupy different positions in the desktop processor landscape, with the Ryzen 9 9900X delivering dominant multi-threaded performance while the Core 7 251TE counters with a notable single-core advantage in certain workloads. The recorded data shows 13 benchmark wins for the AMD part against 2 for the Intel part, but the nature of those wins reveals a clear use-case split.

Where Each One Wins

The AMD Ryzen 9 9900X wins overwhelmingly in heavy parallel workloads. In Cinebench R23 multi-core, it scores 32,172 versus 25,518 for the Intel Core 7 251TE, a 26.1% advantage. The gap widens dramatically in PassMark's multi-thread test, where AMD leads 54,643 to 30,022, a margin of 82%. Data compression shows the largest relative difference: AMD scores 683,579 against Intel's 334,399, which is 104.4% higher. Extended instruction throughput is even more lopsided, with AMD at 55,243 versus Intel's 16,974, a 225.5% delta. Prime number finding favors AMD by 211.4% (436 versus 140). Clearly, the Ryzen 9 9900X is the processor for rendering, simulation, compression, and any workload that scales across many threads.

The Intel Core 7 251TE wins in two specific single-core tests, both from Cinebench. In Cinebench R15 single-core, Intel scores 362 versus AMD's 353, a modest 2.5% edge. In Cinebench R23 single-core, the Intel advantage is much larger: 3,602 versus 2,253, representing a 37.5% lead. This suggests that in lightly threaded legacy workloads, particularly those that respond to Cinebench's single-core scoring, the Intel part can outperform the AMD chip despite having a much lower base clock. However, in PassMark's single-thread test, AMD wins 4,672 to 3,568, a 30.9% margin, which complicates the picture. The Intel part's single-core win is specific to Cinebench's methodology rather than universal across all single-threaded applications.

Architecture Differences

The two processors are built on fundamentally different designs. The AMD Ryzen 9 9900X uses the Zen 5 architecture, codenamed Granite Ridge, fabricated on TSMC's 4 nm process. It integrates 16,630 million transistors across a die size of 2x 70.6 mm². The Intel Core 7 251TE uses the Bartlett Lake codename on Intel's 10 nm process, with a die size of 215 mm². The manufacturing process difference explains part of the performance gap: the smaller node allows AMD to pack more computational resources into less silicon area.

Core counts differ substantially. The AMD part has 12 cores and 24 threads, while the Intel part has 24 cores and 32 threads. Despite having half the cores, AMD wins most multi-threaded benchmarks, which indicates that Zen 5's per-core throughput is far superior to the Bartlett Lake cores in heavily threaded workloads. The Intel part's higher core count does not translate into a performance advantage in the recorded tests.

Cache configurations also diverge. Both processors have 80 KB of L1 cache per core. AMD provides 1 MB L2 per core and 64 MB of L3 cache. Intel provides 1.25 MB L2 per core and 36 MB of shared L3. The larger L3 on AMD likely contributes to its data compression and encryption wins, where larger working sets benefit from more on-die storage.

Clock speeds show a different tradeoff. The AMD part has a base clock of 4.40 GHz and a boost clock of 5.60 GHz with a 120 W TDP. The Intel part has a base clock of 1.40 GHz and a boost clock of 5.40 GHz with a 45 W TDP. The Intel chip's very low base clock is a design choice for efficiency, but it means sustained all-core workloads will run at lower frequencies than the AMD part. The AMD chip's higher base clock allows it to maintain higher performance without relying on boost behavior.

Memory support differs as well. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity favors AMD with Gen 5 and 24 lanes versus Intel's Gen 5 and 16 lanes. Integrated graphics also differ: AMD has Radeon Graphics, Intel has UHD Graphics 770.

The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD processor uses Socket AM5, whereas Intel uses Socket 1700.

Head-to-Head Benchmarks

The multi-core Cinebench R15 test shows AMD at 5,008 versus Intel at 2,572, a 94.7% delta. This near-doubling of score reflects both the core efficiency advantage and the higher sustained clocks of the AMD part. Cinebench R23 multi-core narrows the relative gap to 26.1%, but AMD still holds a decisive lead of 6,654 points.

Single-core Cinebench results flip the script. In Cinebench R15, Intel wins 362 to 353, a 2.5% margin. In Cinebench R23, Intel wins 3,602 to 2,253, a 37.5% margin. These are the only two tests Intel wins, and both come from the same benchmark suite. The magnitude of the R23 single-core win is significant, but it does not carry over to PassMark single-thread, where AMD leads 4,672 to 3,568, a 30.9% advantage.

PassMark's specialized tests heavily favor AMD. Data encryption shows AMD at 33,421 versus Intel's 22,176, a 50.7% lead. Floating point math favors AMD 120,083 to 85,607, a 40.3% margin. Integer math shows AMD at 181,056 versus 125,739, a 44% delta. Random string sorting gives AMD 72,013 versus Intel's 39,643, an 81.7% advantage. Physics simulation favors AMD 3,381 to 1,938, a 74.5% lead. The extended instructions test is the most extreme: AMD's 55,243 is 225.5% higher than Intel's 16,974, indicating a massive advantage in SIMD and vectorized workloads.

The overall average benchmark score tells the same story. AMD's average is 57,498, placing it at the 92nd percentile of all CPUs. Intel's average is 41,650, at the 88th percentile. AMD's nearest rivals in the database include the AMD EPYC 9015 (average 57,555, delta -0.1%), the AMD EPYC 7313 (average 57,399, delta 0.2%), the Intel Core i9-14900 (average 58,115, delta -1.1%), and the Intel Xeon Platinum 8260M (average 58,323, delta -1.4%). Intel's nearest rivals include the Intel Core Ultra 7 265H (average 41,621, delta 0.1%), the Intel Core i7-14650HX (average 41,576, delta 0.2%), the Intel Core i7-12850HX (average 41,779, delta -0.3%), and the Intel Core i7-14700T (average 41,914, delta -0.6%).

The Verdict

The data indicates that the AMD Ryzen 9 9900X is the superior processor for almost all compute-intensive tasks. It wins 13 of 15 head-to-head tests, including all PassMark sub-tests and both Cinebench multi-core tests. The average benchmark score difference is substantial: AMD's 57,498 versus Intel's 41,650, a gap of roughly 38% based on the recorded averages. AMD also sits at the 92nd percentile versus the 88th percentile for Intel.

The Intel Core 7 251TE wins only in Cinebench single-core tests, with the R23 result being particularly strong at a 37.5% margin. Users who run applications that are strictly single-threaded and sensitive to Cinebench-style scoring might see a benefit from the Intel part. However, the PassMark single-thread result contradicts this, showing AMD ahead by 30.9%. The Intel part's 45 W TDP and lower base clock make it a more power-conscious choice, but the recorded benchmarks do not include power measurements, so efficiency cannot be quantified from this data.

The Intel part's 24 cores and 32 threads do not compensate for the architectural advantages of the AMD part. Despite having double the core count, Intel loses multi-threaded tests by margins ranging from 26.1% to 225.5%. The AMD part's 64 MB L3 cache, 5.60 GHz boost clock, and Zen 5 architecture deliver consistently higher throughput.

For users prioritizing multi-threaded rendering, compression, encryption, or scientific computing, the AMD Ryzen 9 9900X is the clear choice based on this data. For users whose workloads are dominated by single-threaded Cinebench-style tasks, the Intel Core 7 251TE offers a specific advantage, but it is narrow and does not generalize across other single-threaded tests.
