AMD Ryzen AI 7 450 vs Intel Core 7 253PE Comparison

Where Each One Wins

The recorded benchmark data splits these two processors into clearly different roles. The Intel Core 7 253PE dominates in raw compute throughput, taking 12 of the 15 head-to-head tests. Its wins are concentrated in heavy multi-threaded workloads, integer and floating-point math, prime number finding, and single-core Cinebench runs. The AMD Ryzen AI 7 450, conversely, wins in exactly three tests: Cinebench R15 multi-core, extended instructions, and random string sorting. These are narrow, workload-specific victories rather than broad performance advantages.

For desktop users running Cinebench R23 multi-core renders, the Intel part leads by 35.8%, scoring 24,880 versus 18,316. That margin is substantial enough to classify the 253PE as the clear choice for content creation and CPU-bound rendering tasks. The AMD part, however, shows a 7.6% lead in the older Cinebench R15 multi-core test, which may reflect different scaling behavior under the shorter workload. In PassMark integer math, the Intel CPU posts 114,158 versus 88,531, a 28.9% advantage, indicating stronger general-purpose number crunching. Floating-point math sees an even larger gap at 48.5% in favor of Intel, with scores of 80,870 versus 54,447.

The AMD Ryzen AI 7 450 wins in extended instructions by 2.7% (22,400 versus 21,806) and in random string sorting by 8.1% (35,648 versus 32,777). These are modest margins, suggesting the Zen 5 architecture has particular strengths in specific instruction paths and memory-access patterns. The single-thread PassMark score is nearly tied: Intel leads by only 1.4% (3,955 versus 3,901). For users prioritizing absolute multi-core throughput, the database clearly favors Intel. For those running mixed workloads with occasional string sorting or extended instruction use, the AMD part offers a competitive alternative at lower power draw.

This is a dominant result, far exceeding the 35.8% multi-core margin in the same test suite. The R23 multi-core score of 24,880 versus 18,316 reinforces that Intel's advantage scales across thread counts, not just in lightly threaded tasks.

PassMark integer math shows a 28.9% Intel lead (114,158 versus 88,531), while floating-point math widens to 48.5% (80,870 versus 54,447). Prime number finding sees a 55.1% gap in favor of Intel (138 versus 89), indicating strong branch prediction and arithmetic throughput. Data encryption favors Intel by 13.2% (18,385 versus 16,247), and data compression by 7.4% (339,133 versus 315,906). The multithread PassMark score is 11.1% higher on Intel (29,271 versus 26,350), and physics simulation shows a 16.9% edge (1,845 versus 1,578).

AMD's wins are smaller in magnitude. The Cinebench R15 multi-core victory is 7.6% (2,713 versus 2,507). Extended instructions show a 2.7% edge (22,400 versus 21,806). Random string sorting is the largest AMD win at 8.1% (35,648 versus 32,777). The single-thread PassMark test is nearly a tie, with Intel ahead by just 1.4% (3,955 versus 3,901). Across all 15 tests, the average benchmark score difference is 2.7% in Intel's favor (40,557 versus 39,485), placing both processors in the same 87th percentile among all CPUs.

Specification Differences

The two processors differ fundamentally in core and thread counts. Intel offers 10 cores and 20 threads, while AMD provides 8 cores and 16 threads. Clock speeds also diverge: Intel has a 2.50 GHz base and 5.50 GHz boost, versus AMD's 2.00 GHz base and 5.10 GHz boost. Thermal design power is a major separation point, with Intel rated at 65 W and AMD at 28 W, reflecting their different market segments.

Socket compatibility is entirely different: Intel uses Socket 1700, AMD uses Socket FP8. The process node also differs, with Intel on a 10 nm process from its own foundry, while AMD uses TSMC's 4 nm process. AMD lists a die size of 195 mm², while Intel does not report one. Cache hierarchies diverge: both have 80 KB L1 per core, but Intel has 2 MB L2 per core versus AMD's 1 MB per core. Intel's shared L3 is 33 MB, while AMD's is 8 MB.

Memory support differs in type: Intel supports DDR4 and DDR5, AMD supports DDR5 and LPDDR5X. Both run dual-channel and share the same 89.6 GB/s bandwidth. Both support ECC memory. PCIe generation differs: Intel provides Gen 5 with 16 CPU lanes, AMD provides Gen 4 with 16 CPU lanes. Integrated graphics are distinct: Intel includes UHD Graphics 730, AMD includes Radeon 860M.

Market placement is opposite: Intel targets desktop, AMD targets mobile. Release dates differ by roughly two months, with AMD launching on January 4, 2026, and Intel on March 8, 2026. Intel has a launch MSRP of $384; AMD has no listed launch MSRP. Neither processor has an unlocked multiplier. The part numbers are SA4QE for Intel and 100-000001868 for AMD.

Architecture Differences

Intel's Core 7 253PE is built on the Bartlett Lake codename, part of the Core 7 generation. The architecture uses a 10 nm process fabricated by Intel's own foundry. The core layout provides 10 cores and 20 threads, with a per-core L2 of 2 MB and a shared L3 of 33 MB. This large last-level cache is a key contributor to the Intel part's strong performance in multi-threaded and data-heavy workloads. The processor supports PCIe Gen 5 with 16 CPU lanes, enabling high-bandwidth peripheral connectivity for desktop platforms.

AMD's Ryzen AI 7 450 uses the Zen 5 architecture, with the Gorgon Point codename. It is manufactured on a 4 nm process at TSMC, with a die size of 195 mm². The processor combines Zen 5 and Zen 5c cores in a hybrid arrangement, though the database only lists total core counts. The L2 is 1 MB per core, and the L3 is 8 MB, which is considerably smaller than Intel's shared cache. AMD supports PCIe Gen 4 with 16 CPU lanes, a generation behind Intel's offering. The Radeon 860M integrated graphics reflect AMD's mobile focus, while Intel pairs its UHD Graphics 730 with a desktop platform.

The TDP difference is stark: 65 W for Intel versus 28 W for AMD. This is not merely a power envelope difference; it also explains why Intel sustains higher boost clocks (5.50 GHz versus 5.10 GHz) and why its multi-core scores are consistently higher. The AMD part, running at lower power, still achieves competitive single-thread PassMark scores (3,901 versus 3,955) and wins in extended instructions and random string sorting, suggesting architectural efficiency rather than brute clock speed.

The cache hierarchy is the most consequential architectural divergence. Intel's 33 MB L3 versus AMD's 8 MB L3, combined with 2 MB per-core L2 versus 1 MB, gives Intel a substantial data locality advantage. This shows in the 55.1% prime number finding win and the 48.5% floating-point math win, both of which depend on repeated access to working sets. AMD's smaller cache may explain its narrow wins in string sorting (8.1%) and extended instructions (2.7%), where specialized instruction paths can compensate for lower cache capacity.

Both processors support ECC memory and dual-channel configurations with identical 89.6 GB/s bandwidth. The memory type differences (DDR4/DDR5 for Intel, DDR5/LPDDR5X for AMD) reflect the platform split between desktop and mobile. Neither processor has an unlocked multiplier, so overclocking is not a differentiator. The production status for both is active, and both sit at the 87th percentile in the database's all-CPU rankings.
