AMD Ryzen 7 170 vs Intel Core 7 251E Comparison

The Verdict

The data presents an unusual comparison: the AMD Ryzen 7 170 is a mobile processor with a complete set of recorded benchmark results, while the Intel Core 7 251E is a desktop part with no benchmark scores in the database. This asymmetry shapes the entire analysis. The AMD part sits at the 88th percentile among all CPUs, with an average benchmark score of 43,689, placing it in a tight cluster with other high-end AMD processors. The Intel part shows a 50th percentile ranking, but its average benchmark score is recorded as zero due to missing test data.

For users selecting a processor strictly from recorded measurements, the AMD Ryzen 7 170 is the only option with verifiable performance data. It competes within 1% of the AMD Ryzen 7 PRO 7745, the AMD Ryzen 7 260, the AMD Ryzen AI 9 465, and the AMD Ryzen AI Max PRO 385, all of which score between 43,326 and 43,717. The Intel Core 7 251E cannot be positioned against these figures because no benchmark results exist for it in the database. The Intel part does offer a higher boost clock, more cores, more threads, and a larger cache, but without measured scores, those specifications cannot be translated into performance claims.

The AMD Ryzen 7 170 is suitable for mobile workloads where its 35 TDP and integrated Radeon 680M graphics matter. The Intel Core 7 251E targets desktop systems with its 65 TDP, Socket 1700 compatibility, and UHD Graphics 770. The choice between them depends on platform and use case, not on benchmark comparison, since the Intel side lacks any recorded test outcomes.

Architecture Differences

The two processors come from different manufacturers, foundries, and process nodes. The AMD Ryzen 7 170 uses the Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC with a die size of 210 mm². The Intel Core 7 251E uses the Bartlett Lake codename, built on a 10 nm process at Intel with a die size of 257 mm². These process differences imply distinct transistor density and power characteristics, though the database does not list transistor counts for either chip.

Core and thread counts diverge sharply. The AMD part has 8 cores and 16 threads. The Intel part has 24 cores and 32 threads, triple the core count and double the thread count of the AMD chip. Clock speeds also differ: the AMD base clock is 3.20 GHz with a boost of 4.75 GHz, while the Intel base clock is 2.10 GHz with a boost of 5.60 GHz. The Intel part has a higher ceiling but a lower floor.

Cache hierarchies are structured differently. The AMD Ryzen 7 170 provides 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. The Intel Core 7 251E provides 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Intel part has substantially more L2 and L3 cache, which could benefit workloads with large working sets, but again, no benchmark data confirms this.

Memory support differs. The AMD part supports DDR5 only, with dual-channel access and a memory bandwidth of 76.8 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, with a higher memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity also differs: the AMD part uses Gen 4 with 20 lanes from the CPU, while the Intel part uses Gen 5 with 16 lanes from the CPU. The Intel part offers a newer PCIe generation but fewer lanes.

Integrated graphics are present in both. The AMD part uses Radeon 680M, while the Intel part uses UHD Graphics 770. The database does not include graphics benchmarks for either, so their relative graphical performance cannot be assessed.

Where Each One Wins

Based on recorded data, the AMD Ryzen 7 170 wins every measurable category because the Intel Core 7 251E has no benchmark scores. The AMD part has 11 recorded PassMark tests covering data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithreading, physics, random string sorting, and single-thread performance. Its multithread score is 20,760, its single-thread score is 3,128, and its integer math score is 79,738. These are the only numbers available for comparison.

For workloads that favor high core counts and large caches, the Intel Core 7 251E has theoretical advantages based on specifications. Its 24 cores, 32 threads, and 36 MB L3 cache suggest strength in heavily parallel tasks, but the database contains no test results to verify this. Its 5.60 GHz boost clock could benefit single-threaded responsiveness, but again, no single-thread score exists for it.

For mobile deployment, the AMD Ryzen 7 170 has clear positioning. Its 35 TDP is lower than the Intel part's 65 TDP, making it more suitable for thermally constrained systems. Its AMD Socket FP7 and mobile market segment confirm this intent. The Intel part is explicitly a desktop processor with Socket 1700, which requires a different platform.

FAQ

Q: Which processor has better recorded benchmark performance?

A: The AMD Ryzen 7 170 is the only one with recorded benchmark scores. Its average benchmark score is 43,689, and it ranks at the 88th percentile among all CPUs. The Intel Core 7 251E has no benchmark data in the database, so no performance comparison is possible.

Q: How does the AMD Ryzen 7 170 compare to its nearest rivals?

A: It sits within 1% of four other AMD processors: the AMD Ryzen 7 PRO 7745 (43,704, delta 0%), the AMD Ryzen 7 260 (43,717, delta -0.1%), the AMD Ryzen AI 9 465 (43,431, delta 0.6%), and the AMD Ryzen AI Max PRO 385 (43,326, delta 0.8%). These are effectively tied scores.

Q: What are the core and thread differences between the two?

A: The AMD Ryzen 7 170 has 8 cores and 16 threads. The Intel Core 7 251E has 24 cores and 32 threads. The Intel part has three times the cores and double the threads.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two processors. The AMD Ryzen 7 170 has its own set of 11 PassMark scores, while the Intel Core 7 251E has none. This means every numerical comparison in this section is one-sided.

The AMD Ryzen 7 170's strongest recorded results include a PassMark multithread score of 20,760 and a PassMark single-thread score of 3,128. Its data compression score is 265,920, which is by far its highest raw number. Its floating point math score is 44,979, and its integer math score is 79,738. The data encryption score is 16,078, extended instructions score is 18,107, random string sorting score is 27,804, and physics score is 890. The find prime numbers score is 49, which is the lowest recorded value.

Because the Intel Core 7 251E has no benchmark scores, the database's wins counter shows 0 wins for both processors. The head-to-head benchmark array is empty. This is not a close contest; it is a contest with only one participant providing data. The Intel part's specifications suggest it could be competitive, especially in multi-threaded workloads given its 24 cores and 32 threads, but the absence of measurements prevents any claim beyond speculation.

The AMD part's percentile ranking of 88 places it above the Intel part's 50th percentile, but the Intel percentile is based on an average score of zero, which likely reflects missing data rather than actual performance. Interpreting that 50th percentile as a real performance indicator would be misleading.
