AMD Ryzen 9 9900X3D vs Intel Core 7 253PTE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep. The AMD Ryzen 9 9900X3D wins all 17 head-to-head benchmark comparisons against the Intel Core 7 253PTE. None of the tested workloads favor Intel. The margins vary dramatically by workload type, from modest single-thread gaps to massive multi-thread and specialized task leads.

Starting with the render-focused Cinebench suite, the AMD part is consistently about 124% ahead. In Cinebench R23 multi-core, the AMD scores 47737 against Intel's 21276. The single-core R23 result shows 6739 versus 3003, a 124.4% delta. The same pattern holds in R20 and R15, where both multi-core and single-core tests show the AMD processor ahead by roughly 124.4%. This consistency suggests the per-core performance advantage is uniform across the board, not dependent on thread count scaling.

The PassMark integer math test shows the smallest multi-thread gap: AMD scores 179727, Intel scores 119552, a 50.3% lead. Floating-point math is closer in percentage terms at 78% (119622 versus 67209), but still a decisive win for AMD. The single-thread PassMark result is the narrowest overall gap: 4646 versus 3794, a 22.5% delta. That is the one test where the Intel part stays within striking distance, though it still loses.

The most lopsided results appear in specialized workloads. PassMark find prime numbers shows AMD at 544 versus Intel at 82, a 563.4% delta. Physics simulation is nearly as extreme: 5340 versus 1318, a 305.2% lead. Extended instructions show AMD at 55426 versus 17099, a 224.1% gap. Random string sorting favors AMD by 154.6% (71864 versus 28227). Data compression shows AMD at 685074 versus 275828, a 148.4% lead. Data encryption is the closest of the specialized tests at 114.7% (33282 versus 15500). The PassMark multi-thread score summarizes the overall thread scaling picture: 56154 versus 25031, a 124.3% advantage.

Where Each One Wins

The benchmark data gives the AMD Ryzen 9 9900X3D a win in every measured category. There is no workload type in the database where the Intel Core 7 253PTE produces a higher score. That said, the size of the gap varies enough to draw practical distinctions.

For single-thread responsiveness, the AMD part leads by 22.5% in PassMark single-thread and 124.4% in Cinebench R23 single-core. The PassMark result is the closest margin anywhere in the dataset, so lightly threaded tasks such as everyday desktop interaction show the smallest relative difference. Still, the AMD processor is faster in absolute terms.

For heavily threaded workloads, the AMD advantage is consistently around 124% in Cinebench and PassMark multi-thread tests. The 12-core, 24-thread configuration handles parallel scaling better than the 10-core, 20-thread Intel part. The gap in physics simulation and prime number finding, both of which stress integer throughput and branch-heavy code, is far larger, in the 300% to 560% range. That points to architectural advantages beyond raw core count.

For data-oriented tasks, the AMD processor shows a 148.4% lead in compression and a 114.7% lead in encryption. Extended instruction throughput is 224.1% higher. These are workloads where the Zen 5 architecture's per-core efficiency and larger cache appear to matter substantially.

The Intel Core 7 253PTE has no winning category in the recorded benchmarks. Its role in a comparison is defined by what it does not lose as badly: single-thread PassMark, where the gap is 22.5%, and floating-point math, where the gap is 78%. Those are still losses, but a builder prioritizing power efficiency might accept the lower performance for the 45 W TDP.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen 9 9900X3D is built on Zen 5 architecture with the Granite Ridge codename, part of the 9000 series. It uses a 4 nm process from TSMC with 16,630 million transistors across a dual-die layout measuring 2x 70.6 mm². The Intel Core 7 253PTE uses the Bartlett Lake codename on a 10 nm Intel process. The database does not list transistor count or die size for the Intel part.

Core topology differs significantly. The AMD processor has 12 cores and 24 threads. The Intel part has 10 cores and 20 threads. Both use 80 KB of L1 cache per core, but the L2 configuration diverges: AMD uses 1 MB per core, while Intel uses 2 MB per core. The L3 cache is the most striking difference. AMD packs 128 MB of L3, while Intel provides 33 MB shared. That 128 MB pool is a major factor in the AMD processor's large leads in data compression and extended instruction tests, where cache capacity directly impacts throughput.

Clock behavior also differs. The AMD base clock is 4.40 GHz with a boost of 5.50 GHz. The Intel base clock is much lower at 1.80 GHz with a boost of 5.40 GHz. The lower Intel base clock reflects its 45 W TDP, versus the 120 W TDP of the AMD part. The boost clocks are close, within 0.10 GHz, but the sustained performance envelope is very different.

Memory support shows a split. Both use dual-channel memory with 89.6 GB/s bandwidth and support ECC. The AMD processor exclusively supports DDR5. The Intel part supports both DDR4 and DDR5, which gives it flexibility for older platform configurations. PCIe connectivity also differs: AMD offers Gen 5 with 24 CPU lanes, while Intel offers Gen 5 with 16 CPU lanes.

Integrated graphics are present on both, but different models. AMD uses Radeon Graphics, while Intel uses UHD Graphics 730. The AMD processor has an unlocked multiplier; the Intel part is locked. The AMD part fits the AMD Socket AM5, while Intel uses Socket 1700. The AMD part has a 2025-01-05 release date; the Intel part is dated 2026-03-08. The Intel part is listed with part number SA4QK, and AMD with part number 100-000001368.

The Verdict

The benchmark data is unambiguous. The AMD Ryzen 9 9900X3D outperforms the Intel Core 7 253PTE in every recorded test. The average benchmark score for the AMD part is 54762, placing it in the 91st percentile of all CPUs. The Intel part averages 34962, which lands in the 84th percentile. The nearest rivals to the AMD part are the Intel Core Ultra 5 245KF at 55093 with a -0.6% delta, the Intel Core Ultra 5 245K at 54053 with a 1.3% delta, the Intel Xeon 6505P at 53701 with a 2% delta, and the Intel Core i7-14700F at 53620 with a 2.1% delta. The nearest rivals to the Intel part are the Intel Core i7-13800H at 34988 with a -0.1% delta, the Intel Core i9-12900HX at 35003 with a -0.1% delta, the Intel Xeon 6349P at 34890 with a 0.2% delta, and the AMD Ryzen 5 150 at 34881 with a 0.2% delta.

For workloads that depend on multi-core throughput, large cache residency, or high sustained clocks, the AMD Ryzen 9 9900X3D is the clear choice. Its 124% lead in Cinebench multi-core and 148% lead in data compression reflect the combination of 12 cores, 24 threads, 128 MB of L3, and a 5.50 GHz boost clock. The 45 W TDP of the Intel part is its primary distinction. Builders prioritizing low power draw over absolute performance, or those needing DDR4 compatibility on Socket 1700, would look at the Intel Core 7 253PTE. Everyone else, the data says, should take the AMD processor. The 22.5% single-thread gap in PassMark is the closest contest, but it is still a win for AMD, and the 305% to 563% margins in physics and prime-number workloads are decisive. The Intel part has no recorded benchmark victory to point to.
