AMD Ryzen Embedded 9950X vs Intel Core Ultra 7 255H Comparison

Head-to-Head Benchmarks

The recorded data set contains no shared benchmark submissions for the AMD Ryzen Embedded 9950X and the Intel Core Ultra 7 255H. The AMD part has an empty benchmark array, while the Intel part carries 19 individual test scores. Consequently, direct head-to-head comparisons cannot be drawn from the database. The Intel Core Ultra 7 255H has measurable scores across Cinebench R15, R20, R23, Geekbench, and Passmark suites, with an average benchmark score of 33,537 and a percentile rank of 83 among all CPUs tracked. The AMD Ryzen Embedded 9950X holds a percentile rank of 50 with an average benchmark score of zero, indicating no recorded performance data at this time.

The Intel Core Ultra 7 255H delivers a Cinebench R23 multicore score of 9,240 and a single-core score of 1,843. In Geekbench, it records 14,024 multicore and 2,335 single-core. Passmark results show a multithread score of 30,703, single-thread of 4,317, floating-point math of 98,796, and integer math of 77,975. The highest Passmark figure is data compression at 298,850, followed by random string sorting at 36,058, extended instructions at 23,755, and data encryption at 23,395. Physics registers 2,254, while finding prime numbers produces 303.

Since the AMD processor lacks any benchmark records, the database cannot establish which unit wins each workload category. The Intel mobile chip stands as the only quantified performer in this pairing. For context, the Core Ultra 7 255H sits near the AMD Ryzen 5 240, which scores 33,542 for a delta of 0 percent. It trails the AMD Ryzen 7 8840HS (33,667) and AMD Ryzen 5 7645HX (33,668) by 0.4 percent each. It leads the Intel Core i5-12600HX (33,375) by 0.5 percent. These nearest-rival deltas frame the Ultra 7 255H as a mid-pack mobile processor, not an outlier in either direction.

Architecture Differences

The two processors diverge fundamentally in platform and design. The AMD Ryzen Embedded 9950X uses the Granite Ridge codename under the Ryzen Embedded Zen 5 generation, built on a 4 nm process at TSMC. It packs 16 cores and 32 threads, with a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The package includes 16,630 million transistors across a dual-die layout of 2x 70.6 mm². Cache is distributed as 80 KB L1 per core, 1 MB L2 per core, and 64 MB L3. The CPU targets the desktop market segment, uses AMD Socket AM5, and features an unlocked multiplier. Its integrated graphics are listed as Radeon Graphics.

The Intel Core Ultra 7 255H belongs to the Core Ultra Series 2, codenamed Arrow Lake-H, fabricated on a 3 nm TSMC process. It has 16 cores and 16 threads, indicating no hyperthreading on this part, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Cache differs sharply: 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. The chip targets the mobile segment, mounts on Intel BGA 2049, and has a locked multiplier. Its integrated graphics are Arc Graphics 140T. Transistor count and die size are not recorded.

Process node favors Intel at 3 nm versus AMD's 4 nm, though both come from TSMC. Clock speeds favor AMD substantially: 4.30 GHz base versus 2.00 GHz, and 5.70 GHz boost versus 5.10 GHz. Thread count favors AMD at 32 versus 16, a direct consequence of simultaneous multithreading on the AMD side. The L3 cache is 64 MB on AMD versus 24 MB on Intel, a 40 MB gap. The L1 and L2 per-core values are larger on Intel, but the shared L3 pool is smaller. Power envelopes differ dramatically: the AMD part carries a 170 W TDP, while the Intel mobile part lists 28 W. That TDP gap reflects different market positioning: desktop versus mobile.

Memory support overlaps on DDR5, but Intel adds LPDDR5X. Both use dual-channel memory buses. Memory bandwidth numbers are 89.6 GB/s for AMD and 102.4 GB/s for Intel, so the Intel part shows a higher theoretical bandwidth despite its lower power target. Both support ECC memory. PCIe capacity differs: AMD provides Gen 5 with 28 CPU lanes, Intel provides Gen 5 with 20 CPU lanes. The AMD part has an unlocked multiplier; the Intel part does not. Release dates are recorded as 2025-10-06 for AMD and 2025-01-12 for Intel, so the Intel chip entered the database earlier. Both carry Active production status.

Where Each One Wins

Based strictly on recorded data, the Intel Core Ultra 7 255H wins every category where numbers exist. It has a benchmark suite spanning rendering, general-purpose compute, and encryption workloads. The AMD Ryzen Embedded 9950X has no measurements, so no workload can be attributed to it from this database.

The Intel part's strengths appear in its Passmark data compression score of 298,850, which dominates its own other Passmark results. Floating-point math at 98,796 and integer math at 77,975 indicate solid compute throughput. Data encryption at 23,395 and extended instructions at 23,755 show balanced cryptographic and SIMD capabilities. The Cinebench R23 multicore score of 9,240 and Geekbench multicore of 14,024 confirm that the 16-thread configuration handles parallel rendering and general workloads adequately for a mobile processor.

The AMD processor's architectural attributes point to potential advantages in heavily threaded desktop workloads, given 32 threads, a 5.70 GHz boost clock, and 64 MB L3. The 170 W TDP and desktop socket support sustained high-frequency operation. The unlocked multiplier allows frequency adjustment. However, none of these advantages are quantified in benchmark scores within the database. The Intel chip, by contrast, demonstrates measurable capability in a 28 W envelope, which suggests efficiency in constrained thermal environments, though the database does not list efficiency ratios.

The Verdict

The data supports the Intel Core Ultra 7 255H as the only measured performer in this comparison. Its benchmark scores span 19 tests, with an average of 33,537 and a percentile rank of 83. The AMD Ryzen Embedded 9950X has no recorded benchmark scores, an average of zero, and a percentile rank of 50. A user requiring quantified results from the database would select the Intel part based on available evidence.

The AMD unit remains a specification-only entry. It offers 32 threads, a 5.70 GHz boost clock, 64 MB L3, and a 170 W TDP, which indicate high-end desktop capability, but no test confirms that capability. The Intel unit offers 16 threads, a 5.10 GHz boost, 24 MB L3, and a 28 W TDP, with confirmed scores in rendering, general compute, and encryption workloads. The choice hinges on whether the buyer needs verifiable performance data or is willing to rely on architectural specifications alone. For database-driven decisions, the Intel Core Ultra 7 255H is the supported pick.
