AMD Ryzen 5 40 vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The benchmark data shows a complete sweep for the Intel Core 7 253PE across all 15 recorded head-to-head tests, taking every single win with no victories recorded for the AMD Ryzen 5 40. The largest gap appears in Cinebench R23 multicore, where the Intel part scores 24,880 against the AMD's 4,841, a delta of -80.5% from the AMD's perspective. That means the Intel processor delivers roughly five times the multicore rendering throughput in this specific workload.

The margin narrows considerably in single-threaded tests, though Intel still holds a commanding lead. In Cinebench R23 singlecore, the Intel chip scores 3,512 versus 1,150 for the AMD, a -67.3% delta. PassMark single-thread shows the Intel part at 3,955 against 2,477, the smallest relative gap in the entire dataset at -37.4%. This indicates that while the Intel processor wins decisively in every category, the AMD's single-core performance is comparatively closer to parity than its multicore showing.

Integer math tells a similar story to the rendering benchmarks. The Intel Core 7 253PE posts 114,158 in PassMark integer math, while the AMD Ryzen 5 40 manages 31,598, a -72.3% delta. Floating-point math shows an even wider split: 80,870 versus 15,194, a -81.2% delta. The AMD's relative weakness in floating-point workloads is consistent with its lower core count and older architecture.

Data compression and encryption workloads follow the same pattern. PassMark data compression scores 339,133 for Intel against 141,533 for AMD, a -58.3% delta. Data encryption shows 18,385 versus 6,646, a -63.9% delta. The compression test is one of the closer multicore comparisons, likely because the AMD's memory bandwidth of 88.0 GB/s, while slightly lower than the Intel's 89.6 GB/s, still allows respectable throughput in memory-bound tasks.

The PassMark physics test, which often scales strongly with thread count, shows the Intel part at 1,845 versus 432 for AMD, a -76.6% delta. Prime number finding, another heavily parallel workload, shows Intel at 138 versus 20, the largest percentage gap in the dataset at -85.5%. Extended instruction set performance lands at 21,806 for Intel and 6,437 for AMD, a -70.5% delta. Random string sorting, a memory-latency-sensitive test, shows 32,777 for Intel and 15,124 for AMD, a -53.9% delta.

The overall average benchmark score places the Intel Core 7 253PE at 40,557, which ranks in the 87th percentile of all CPUs in the database. The AMD Ryzen 5 40 averages 15,882, putting it in the 70th percentile. The nearest rivals for the Intel part include the Intel Core 5 223PE at 40,585 (-0.1% delta), the Intel Core Ultra X7 368H at 40,518 (+0.1%), the Intel Xeon 6357P at 40,630 (-0.2%), and the AMD Ryzen 9 7940H at 40,431 (+0.3%). The AMD Ryzen 5 40's nearest rivals include the AMD EPYC 75F3 at 15,859 (+0.1%), the Intel Core Ultra 5 134U at 15,910 (-0.2%), the AMD EPYC 9354P at 15,826 (+0.4%), and the AMD EPYC 9334 at 15,940 (-0.4%).

Architecture Differences

The two processors come from different manufacturing and design generations. The AMD Ryzen 5 40 uses TSMC's 6 nm process node and is built on the Zen 2 architecture under the Mendocino codename. It has 4 cores and 8 threads. The Intel Core 7 253PE uses Intel's own 10 nm process node and is built on the Bartlett Lake codename under the Core 7 generation label. It has 10 cores and 20 threads, giving it 6 more cores and 12 more threads than the AMD part.

Cache configurations diverge significantly. The AMD Ryzen 5 40 has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel Core 7 253PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Intel part's L3 cache is over eight times larger, and its per-core L2 cache is four times larger. This cache advantage likely contributes to its higher single-thread scores in memory-sensitive workloads.

Clock speeds also differ notably. The AMD part has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The Intel part has a lower base clock of 2.50 GHz but a substantially higher boost clock of 5.50 GHz, a 1.20 GHz advantage in maximum frequency. The AMD's higher base clock does not translate into benchmark wins, as the Intel's higher boost ceiling and larger core count dominate.

Platform support separates the two as well. The AMD Ryzen 5 40 uses AMD Socket FT6 and targets the mobile segment. The Intel Core 7 253PE uses Intel Socket 1700 and targets the desktop segment. Memory support differs: the AMD part supports LPDDR5 only, while the Intel part supports both DDR4 and DDR5. Both use dual-channel memory buses, with the AMD rated at 88.0 GB/s and the Intel at 89.6 GB/s. ECC memory is not supported on the AMD part but is supported on the Intel part.

PCIe capabilities differ sharply. The AMD Ryzen 5 40 provides PCIe Gen 3 with 4 lanes (CPU only), while the Intel Core 7 253PE provides PCIe Gen 5 with 16 lanes (CPU only). The Intel part's four times the lane count and two generations newer PCIe standard give it far greater expansion and I/O bandwidth potential. Integrated graphics also differ: the AMD uses Radeon 610M, while the Intel uses UHD Graphics 730.

The Intel part carries a launch MSRP of $384. The AMD part has no recorded launch MSRP in the database. The Intel part has a TDP of 65 watts, while the AMD part has a TDP of 15 watts. Neither processor has an unlocked multiplier. The AMD die size is recorded at 100 mm², while the Intel die size is not recorded. The Intel part number is SA4QE; the AMD part number is unknown.

The Verdict

The benchmark data is unambiguous: the Intel Core 7 253PE wins every recorded comparison. Its 87th percentile standing against the AMD's 70th percentile reflects a substantial overall performance gap. The Intel part's average benchmark score of 40,557 is more than 2.5 times the AMD's 15,882. Anyone selecting between these two strictly on performance data should choose the Intel part.

The AMD Ryzen 5 40 does have one clear advantage in the recorded specifications: power consumption. Its 15 watt TDP is 50 watts lower than the Intel part's 65 watt TDP. For systems where thermal and power budgets are the primary constraint, the AMD part would be the sensible selection. The AMD part also uses the 6 nm process node, which is smaller than the Intel's 10 nm node, though this does not produce a performance benefit in the recorded benchmarks.

The Intel part offers ECC memory support, which the AMD part lacks. This makes the Intel part relevant for systems requiring error-correcting memory. The Intel part's PCIe Gen 5 with 16 lanes also makes it more suitable for high-bandwidth expansion cards, while the AMD part's PCIe Gen 3 with 4 lanes limits it to lighter I/O configurations.

Where Each One Wins

The Intel Core 7 253PE wins in every performance category recorded. Its largest advantages appear in heavily parallel workloads: prime number finding shows a -85.5% delta, floating-point math shows -81.2%, and Cinebench R23 multicore shows -80.5%. These tests benefit directly from the Intel part's 10 cores and 20 threads against the AMD's 4 cores and 8 threads. The physics test, which also scales with thread count, shows a -76.6% delta in Intel's favor.

The Intel part's smallest advantages are in single-threaded tests. PassMark single-thread shows -37.4%, and Cinebench R15 singlecore shows -53.2%. These tests rely less on core count and more on clock speed and architecture efficiency. The Intel's 5.50 GHz boost clock gives it a meaningful edge over the AMD's 4.30 GHz boost, but the AMD's Zen 2 architecture keeps the gap from widening further.

The AMD Ryzen 5 40's advantage lies outside raw performance. Its 15 watt TDP makes it suitable for power-constrained mobile designs, and its 6 nm process node from TSMC gives it a smaller lithography than the Intel's 10 nm. The AMD part also records a die size of 100 mm², while the Intel part's die size is not recorded. For systems prioritizing low power draw over performance, the AMD part holds the only measurable advantage in the dataset.

Memory bandwidth is nearly identical between the two, with the Intel part at 89.6 GB/s and the AMD at 88.0 GB/s, a difference of 1.6 GB/s. This close bandwidth figure explains why the compression test, which is partially memory-bound, shows one of the smaller deltas at -58.3%. The Intel part's larger L3 cache of 33 MB against 4 MB likely matters more in cache-sensitive workloads than the small bandwidth difference.

The Intel part also wins on platform features. Its PCIe Gen 5 with 16 lanes dwarfs the AMD's PCIe Gen 3 with 4 lanes. Its support for both DDR4 and DDR5 memory gives it broader memory compatibility than the AMD's LPDDR5-only support. ECC memory support on the Intel part adds another capability the AMD part lacks. These specification differences, combined with the benchmark sweep, make the Intel Core 7 253PE the clear choice for any performance-oriented build, while the AMD Ryzen 5 40 remains relevant only for low-power mobile systems where its 15 watt TDP is the deciding factor.
