AMD Ryzen 7 8700G vs Intel Core 7 251E Comparison

Where Each One Wins

The AMD Ryzen 7 8700G and Intel Core 7 251E occupy different positions in the desktop CPU landscape, and the recorded data shows a clear split in their intended use cases. The Ryzen 7 8700G belongs to AMD's 8000 series and sits in the 83rd percentile of all CPUs in the database, with an average benchmark score of 33,089. The Core 7 251E, built on Bartlett Lake for Intel Socket 1700, sits lower in the 50th percentile, and the database contains no benchmark scores for it, which means its performance characteristics must be inferred from its architecture and specifications alone.

The use-case split favors the Ryzen 7 8700G for any workload where measured performance matters. It has 22 recorded benchmark scores spanning 3DMark, Cinebench, Geekbench, and PassMark tests. These cover single-thread, multi-thread, physics, integer math, floating-point math, data compression, encryption, and prime number finding. The Core 7 251E has no recorded scores, so the data cannot confirm any workload where it would win outright. Its advantage would have to come from its higher core count, larger cache, and faster boost clock, but none of that is verified by measurements.

For gaming and graphics-adjacent tasks, the Ryzen 7 8700G includes a Radeon 780M integrated GPU, while the Core 7 251E uses UHD Graphics 770. The database shows the Ryzen part scoring 7,918 in 3DMark with 16 threads and 6,589 with 8 threads, which indicates strong multi-threaded graphics-related performance. The Intel part has no comparable data.

For productivity and content creation, the Ryzen 7 8700G delivers a Cinebench R23 multicore score of 17,128 and a Geekbench multicore score of 14,584. These numbers place it ahead of the Core 7 251E in every measured category, simply because the Intel part has no measurements to contest them. The Core 7 251E offers 24 cores and 32 threads, which could theoretically favor heavily parallel workloads, but without benchmark data, that remains speculative.

Architecture Differences

The fundamental architectural split between these two processors is substantial. The Ryzen 7 8700G uses AMD's Zen 4 architecture under the Phoenix codename, fabricated on TSMC's 4 nm process. It packs 25,000 million transistors into a 178 mm² die. The Core 7 251E uses Intel's Bartlett Lake codename on a 10 nm process from Intel's own foundry, with a larger 257 mm² die and no transistor count listed in the database.

Cache hierarchies differ sharply. The Ryzen 7 8700G provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Core 7 251E provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. That means the Intel part has 20 KB more L1 per core, double the L2 per core, and more than double the L3 cache overall. Larger caches often help with repeated data access patterns, but the database has no benchmark results to confirm whether this translates into measured wins.

Memory support also differs. The Ryzen 7 8700G supports DDR5 only, with dual-channel memory and a bandwidth of 83.2 GB/s. The Core 7 251E supports both DDR4 and DDR5, also dual-channel, with a higher bandwidth of 89.6 GB/s. The Intel part also supports ECC memory, while the AMD part does not. ECC support matters for certain workstation or server-style workloads, and this is a concrete feature difference where the Intel part has an advantage on paper.

PCIe connectivity differs as well. The Ryzen 7 8700G provides Gen 4 with 20 lanes from the CPU, while the Core 7 251E provides Gen 5 with 16 lanes. Gen 5 offers double the bandwidth per lane, but the AMD part has four more lanes. For storage and expansion, the Intel part's newer PCIe standard could be useful, but again, no measured data confirms real-world impact.

The Ryzen 7 8700G has an unlocked multiplier, meaning overclocking is possible. The Core 7 251E does not have an unlocked multiplier. The AMD part also uses AMD Socket AM5, while the Intel part uses Intel Socket 1700, so platform choice is dictated by motherboard compatibility.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the Core 7 251E has zero recorded benchmark scores. This makes direct numeric comparison impossible. However, the Ryzen 7 8700G's individual scores provide a baseline for what the database measures.

In 3DMark, the Ryzen 7 8700G scores 1,010 in single-thread, 1,978 in 2-thread, 3,825 in 4-thread, 6,589 in 8-thread, 7,918 in 16-thread, and 7,917 in max-thread tests. The scaling from 8-thread to 16-thread shows a gain of 1,329 points, while moving from 16-thread to max-thread yields essentially nothing, a drop of one point. This suggests the processor's 8 cores and 16 threads are fully utilized by 16 threads, with no additional headroom.

In Cinebench R23, the Ryzen 7 8700G scores 1,817 single-core and 17,128 multicore. The ratio between them is roughly 9.4x, which indicates strong multi-thread scaling across its 8 cores. The R15 results show 286 single-core and 2,693 multicore, a similar pattern.

Geekbench shows 2,337 single-core and 14,584 multicore. PassMark tests reveal specific strengths: integer math at 103,107, floating-point math at 63,815, extended instructions at 29,067, data compression at 386,811, and data encryption at 22,842. The single-thread PassMark score is 3,928, and the multithread score is 31,690. Prime number finding is relatively low at 103, while random string sorting reaches 46,025 and physics reaches 1,647.

The nearest rivals for the Ryzen 7 8700G include the Intel Core i7-13650HX with an identical average score of 33,089 and a delta of 0 percent, the AMD Ryzen 7 7745HX at 33,091 with a 0 percent delta, the AMD Ryzen 7 7800X3D at 33,079 with a 0 percent delta, and the AMD Ryzen 9 PRO 6950H at 33,201 with a delta of -0.3 percent. This puts the Ryzen 7 8700G in a tightly packed performance band where four other processors score within 0.3 percent. The Core 7 251E does not appear in any rival list, and its average benchmark score is recorded as zero.

The Verdict

The data clearly favors the AMD Ryzen 7 8700G for anyone who wants measured, verified performance. It has 22 benchmark scores across multiple test suites, an 83rd percentile ranking, and an average benchmark score of 33,089. It matches the Intel Core i7-13650HX and AMD Ryzen 7 7745HX exactly at 33,089 and 33,091 respectively, and it sits within 0.3 percent of the AMD Ryzen 9 PRO 6950H. These are strong results for a desktop processor.

The Intel Core 7 251E offers a larger core count, more cache, higher boost clock, PCIe Gen 5, ECC memory support, and a higher launch MSRP of $384. But the database records no benchmark scores for it, and its 50th percentile ranking places it well below the Ryzen 7 8700G in overall standing. Without measurements, any claim about its performance advantage remains unverified.

The Ryzen 7 8700G also brings a Radeon 780M integrated GPU, an unlocked multiplier, a smaller die, a more advanced 4 nm process, and a lower launch MSRP of $329. Its benchmarks show strong single-thread performance at 1,817 in Cinebench R23 and 2,337 in Geekbench, and robust multi-thread performance at 17,128 and 14,584 respectively.

The Core 7 251E's 24 cores and 32 threads suggest potential for heavily threaded workloads, and its 36 MB of L3 cache and 89.6 GB/s memory bandwidth provide theoretical advantages. But the database contains no data to confirm these translate into real wins. The recorded evidence points to the Ryzen 7 8700G as the measured performer, while the Core 7 251E remains an unverified specification sheet. Based strictly on the data, the Ryzen 7 8700G is the processor with demonstrated results, and the Core 7 251E is the one with untested potential.
