AMD Ryzen 9 9900X vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall advantage for the AMD Ryzen 9 9900X, which claims 13 of the 15 shared benchmark wins. The Intel Core 7 253PE manages only two wins, both in single-threaded Cinebench tests, but the margins in the AMD victories are frequently massive.

The largest single gap appears in PassMark's find prime numbers test. The AMD Ryzen 9 9900X scores 436 against Intel's 138, a delta of 215.9%. This is a workload that scales aggressively with core count and memory bandwidth, and the AMD part's 12 cores and 24 threads simply overwhelm the Intel part's 10 cores and 20 threads. The extended instructions test shows a similar pattern: AMD scores 55,243 versus Intel's 21,806, a 153.3% advantage, indicating substantially better throughput on AVX-style and other extended instruction workloads.

Data compression is another area where the AMD chip doubles the Intel result. The Ryzen 9 9900X posts 683,579 in PassMark's data compression test, while the Core 7 253PE manages 339,133, a delta of 101.6%. Random string sorting follows the same trend with a 119.7% delta (72,013 versus 32,777). These tests are heavily dependent on cache hierarchy and core scaling, and the AMD part's 64 MB of L3 cache versus Intel's 33 MB is a significant structural factor.

In Cinebench R23 multi-core, the AMD Ryzen 9 9900X scores 32,172 against Intel's 24,880, a 29.3% lead. The Cinebench R15 multi-core test shows an even starker gap: 5,008 versus 2,507, a 99.8% delta. This near-doubling in the older Cinebench release reflects how the AMD part's higher base clock (4.40 GHz versus 2.50 GHz) and thread count combine to dominate heavily threaded rendering workloads.

PassMark multi-thread gives AMD a 86.7% lead (54,643 versus 29,271). Integer math shows a 58.6% delta (181,056 versus 114,158), and floating-point math a 48.5% delta (120,083 versus 80,870). The physics test, which often stresses both CPU and memory, shows an 83.3% advantage for AMD (3,381 versus 1,845). Data encryption delivers an 81.8% delta (33,421 versus 18,385), indicating the AMD part handles cryptographic workloads with substantially more headroom.

The two Intel wins are narrow in one case and substantial in another. In Cinebench R15 single-core, Intel scores 354 versus AMD's 353, a delta of only 0.3%, essentially a statistical tie. But in Cinebench R23 single-core, Intel wins clearly with 3,512 versus AMD's 2,253, a 35.8% advantage. This is a notable outlier, as PassMark single-thread shows AMD ahead by 18.1% (4,672 versus 3,955). The discrepancy suggests that the Cinebench R23 single-core test is particularly sensitive to Intel's higher boost clock (5.50 GHz versus 5.60 GHz for AMD, though Intel's architecture appears to sustain that boost more effectively in this specific workload) or to differences in instruction scheduling.

The average benchmark scores in the database confirm the overall picture. The AMD Ryzen 9 9900X has an average score of 57,498, placing it in the 92nd percentile of all CPUs. The Intel Core 7 253PE averages 40,557, in the 87th percentile. The AMD part's nearest rivals are the AMD EPYC 9015 (avg score 57,555, delta -0.1%), the AMD EPYC 7313 (avg score 57,399, delta 0.2%), the Intel Core i9-14900 (avg score 58,115, delta -1.1%), and the Intel Xeon Platinum 8260M (avg score 58,323, delta -1.4%). The Intel Core 7 253PE sits among the Intel Core 5 223PE (avg 40,585, delta -0.1%), Intel Core Ultra X7 368H (avg 40,518, delta 0.1%), Intel Xeon 6357P (avg 40,630, delta -0.2%), and AMD Ryzen 9 7940H (avg 40,431, delta 0.3%).

The Verdict

The data points to two clearly different performance tiers. The AMD Ryzen 9 9900X delivers a substantially higher average benchmark score (57,498 versus 40,557) and wins 13 of 15 head-to-head tests. Its multi-threaded performance is consistently 29% to 216% ahead of the Intel Core 7 253PE across rendering, compression, encryption, and math workloads. The Intel part wins only in single-core Cinebench R23, where it leads by 35.8%, and ties in Cinebench R15 single-core.

For workloads that use many threads, the AMD Ryzen 9 9900X is the only choice between these two. The data shows a 29.3% lead in Cinebench R23 multi-core, a 99.8% lead in Cinebench R15 multi-core, and an 86.7% lead in PassMark multi-thread. The Intel Core 7 253PE does not close this gap in any multi-threaded test.

For single-threaded workloads, the choice depends on the specific benchmark. The Intel part wins Cinebench R23 single-core by a wide margin (35.8%), but AMD wins PassMark single-thread by 18.1%. The Cinebench R15 single-core result is a near tie (0.3% delta). If the primary application is known to correlate with Cinebench R23 single-core, the Intel part has an edge. Otherwise, the AMD part is at least competitive and often ahead.

The Intel Core 7 253PE does have lower power consumption on paper (65 W TDP versus 120 W), and it supports both DDR4 and DDR5 memory, while the AMD part is DDR5-only. But the benchmark data does not show any performance advantage from those features. The Intel part also has a more recent release date (2026-03-08 versus 2024-08-14), but the recorded performance does not reflect that newer timing.

Where Each One Wins

AMD Ryzen 9 9900X wins in:

• Random string sorting: 72,013 versus 32,777 (119.7% delta)
• PassMark single-thread: 4,672 versus 3,955 (18.1% delta)

Intel Core 7 253PE wins in:

• Cinebench R23 single-core: 3,512 versus 2,253 (35.8% delta)
• Cinebench R15 single-core: 354 versus 353 (0.3% delta, effectively a tie)

The AMD part's wins span both throughput and latency-sensitive workloads. The Intel part's two wins are both in single-threaded Cinebench, which suggests a specific architectural advantage in that rendering path, but it does not generalize to other single-threaded tests.

Architecture Differences

The two CPUs come from different manufacturing and design lineages. The AMD Ryzen 9 9900X uses the Zen 5 architecture with the Granite Ridge codename, built on a 4 nm process at TSMC. It integrates 16,630 million transistors across a dual-chip design with a die size of 2x 70.6 mm². The Intel Core 7 253PE uses the Bartlett Lake codename, built on a 10 nm process at Intel's own foundry. The database does not list transistor counts or die size for the Intel part.

The core configurations differ significantly. AMD uses 12 cores and 24 threads, while Intel uses 10 cores and 20 threads. The AMD part has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The Intel part has a base clock of 2.50 GHz and a boost clock of 5.50 GHz. The higher base clock on the AMD part contributes to its strong multi-threaded showing, while the similar boost clocks suggest both reach comparable peak frequencies.

Cache hierarchies diverge as well. Both use 80 KB L1 per core, but AMD provides 1 MB L2 per core versus Intel's 2 MB per core. However, AMD's L3 is 64 MB, nearly double Intel's 33 MB shared L3. This larger L3 likely contributes to the AMD part's advantages in data compression (101.6% delta) and random string sorting (119.7% delta), where working sets can exceed smaller caches.

Memory support differs in flexibility. The Intel part accepts both DDR4 and DDR5, while the AMD part is DDR5-only. Both use a dual-channel bus with 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity differs: AMD offers Gen 5 with 24 lanes (CPU only), while Intel offers Gen 5 with 16 lanes (CPU only).

The sockets and platforms are incompatible. AMD uses Socket AM5, while Intel uses Socket 1700. The AMD part has an unlocked multiplier, allowing overclocking, while the Intel part is locked. The AMD part's launch MSRP is $499, and the Intel part's launch MSRP is $384. The market segment for both is desktop, and both are active production parts.

The manufacturing process difference (4 nm versus 10 nm) explains why the AMD part fits 12 cores with a 120 W TDP, while the Intel part uses 10 cores in a 65 W TDP. The Intel part's lower TDP is notable, but the benchmark data does not show any performance-per-watt advantage in the recorded scores. The release dates differ by about 19 months, with Intel's part launching later (2026-03-08 versus 2024-08-14), yet the older AMD design still dominates the performance charts.
