AMD Ryzen Embedded 9950X vs Intel Core Ultra 7 265HX Comparison

AMD Ryzen Embedded 9950X and Intel Core Ultra 7 265HX represent two distinct approaches to high-performance computing, one aimed at stationary desktop environments and the other at high-end mobile platforms. The AMD part is a 16-core, 32-thread Granite Ridge processor with a 170 W TDP, while the Intel chip is a 20-core, 20-thread Arrow Lake-HX mobile processor with a 55 W TDP. The database contains benchmark results for the Intel Core Ultra 7 265HX, placing it in the 93rd percentile of all CPUs, with an average benchmark score of 63173. Its nearest rivals include the Intel Core i7-13790F, which scores 63080 (0.1% slower), the AMD Ryzen AI 7 450G, which scores 63331 (0.2% faster), the AMD Ryzen AI Embedded P185, which scores 62839 (0.5% slower), and the Intel Core Ultra 7 255HX, which scores 62738 (0.7% slower). No benchmark scores are recorded for the AMD Ryzen Embedded 9950X, so this analysis focuses on the architectural and specification differences between the two, alongside the measured performance of the Intel part.

Where Each One Wins

The Intel Core Ultra 7 265HX is the only one of the two processors with recorded benchmark data, so the performance section of this comparison is defined entirely by its results. The data shows a processor that performs strongly across both single-threaded and multi-threaded workloads, with a single-thread score of 4500 in PassMark and a multi-thread score of 47985. In Cinebench R23, it scores 5737 in single-core and 40642 in multi-core, indicating a balanced design that does not sacrifice lightly threaded responsiveness for heavy parallel throughput.

The AMD Ryzen Embedded 9950X, by contrast, has no benchmark entries in the database, meaning its wins cannot be quantified from recorded measurements. Its strengths must be inferred from its specifications alone. The chip carries 16 cores and 32 threads, which gives it a thread count 60% higher than the Intel part, and it boosts to 5.70 GHz compared to the Intel chip's 5.30 GHz. The AMD processor also offers 64 MB of L3 cache versus the Intel chip's 30 MB, a difference that typically favors cache-sensitive workloads. The AMD part is built for desktop sockets, with a 170 W TDP, and includes ECC memory support, which the Intel mobile chip lacks.

The practical split is therefore clear. For mobile systems where power draw and package size matter, the Intel Core Ultra 7 265HX is the part with measured results and a 55 W TDP. For embedded desktop applications that require high thread counts, large L3 cache, and ECC memory, the AMD Ryzen Embedded 9950X brings those features in its specifications. The Intel part's recorded performance places it above or near several rivals, including a 0.7% lead over the Intel Core Ultra 7 255HX and a 0.5% lead over the AMD Ryzen AI Embedded P185, while sitting just 0.2% behind the AMD Ryzen AI 7 450G.

Architecture Differences

The two processors come from different architectural lineages and manufacturing processes. The AMD Ryzen Embedded 9950X uses the Granite Ridge codename, part of the Ryzen Embedded Zen 5 generation, and is fabricated on a 4 nm process at TSMC. The Intel Core Ultra 7 265HX uses the Arrow Lake architecture, specifically Arrow Lake-HX, and is fabricated on a 3 nm process, also at TSMC. Both share the same foundry, but the Intel chip uses a smaller process node.

Transistor counts differ slightly, with the AMD part carrying 16,630 million transistors across a die size of 2x 70.6 mm², while the Intel chip packs 17,800 million transistors into a single 243 mm² die. The AMD processor uses a chiplet design, indicated by the dual-die layout, whereas the Intel processor appears as a single monolithic die. The AMD chip's cache hierarchy features 80 KB of L1 per core and 1 MB of L2 per core, with 64 MB of L3 cache. The Intel chip has 192 KB of L1 per core and 3 MB of L2 per core, but only 30 MB of shared L3 cache. The Intel part's larger per-core L1 and L2 allocations contrast with the AMD part's much larger total L3 pool.

Memory support shows another architectural divergence. Both processors support DDR5 and dual-channel memory, but the AMD chip lists a memory bandwidth of 89.6 GB/s while the Intel chip lists 102.4 GB/s. The AMD part supports ECC memory, a feature absent from the Intel mobile chip. PCIe connectivity also differs, with the AMD processor offering Gen 5 with 28 lanes from the CPU, while the Intel chip offers Gen 5 with 20 lanes from the CPU. Integrated graphics differ as well, with the AMD part using Radeon Graphics and the Intel part using Arc Xe-LPG Graphics with 64 execution units.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database contains no direct comparison entries between the AMD Ryzen Embedded 9950X and the Intel Core Ultra 7 265HX. All recorded performance data belongs to the Intel processor, which has a substantial set of Cinebench and PassMark results. In Cinebench R15, the Intel chip scores 4096 in multi-core and 578 in single-core. In Cinebench R20, it scores 17069 in multi-core and 2409 in single-core. In Cinebench R23, it scores 40642 in multi-core and 5737 in single-core. These results show a processor that scales well from single-threaded to multi-threaded workloads, with the R23 multi-core score roughly seven times the single-core score.

PassMark results for the Intel chip cover a range of specialized workloads. The data compression test yields a score of 511817, while data encryption scores 39472. Extended instructions score 40741, and the find prime numbers test scores 406. Floating point math scores 161605, integer math scores 126954, and random string sorting scores 62458. The physics test scores 2978. The single-thread score of 4500 and multi-thread score of 47985 round out the suite. These numbers indicate a processor that is particularly strong in data compression and math-heavy tasks, with encryption and prime number finding as relatively weaker areas.

Relative to its nearest recorded rivals, the Intel Core Ultra 7 265HX shows a tight grouping. It is 0.1% faster than the Intel Core i7-13790F, 0.5% faster than the AMD Ryzen AI Embedded P185, and 0.7% faster than the Intel Core Ultra 7 255HX. It is 0.2% slower than the AMD Ryzen AI 7 450G. The differences are small, placing the 265HX in a competitive band with those processors. The AMD Ryzen Embedded 9950X has no such data, so no numerical comparison of its performance against the Intel chip or any other processor can be made from the database.

Specification Differences

The two processors differ across nearly every major specification field. The AMD Ryzen Embedded 9950X has 16 cores and 32 threads, while the Intel Core Ultra 7 265HX has 20 cores and 20 threads. The AMD part's base clock is 4.30 GHz and boost clock is 5.70 GHz, while the Intel part's base clock is 2.60 GHz and boost clock is 5.30 GHz. TDP differs substantially, with the AMD chip rated at 170 W and the Intel chip at 55 W. The AMD processor uses AMD Socket AM5, a desktop socket, while the Intel processor uses Intel BGA 2114, a mobile socket.

Cache configurations diverge sharply. The AMD chip provides 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Intel chip provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Memory bandwidth favors the Intel chip at 102.4 GB/s versus 89.6 GB/s for AMD. ECC memory support is present on the AMD chip but absent on the Intel chip. PCIe lanes favor AMD with 28 Gen 5 lanes versus 20 Gen 5 lanes for Intel.
