AMD Ryzen 7 5800XT vs AMD Ryzen AI Embedded P164 Comparison

Head-to-Head Benchmarks

The recorded PassMark data shows a clear overall victory for the AMD Ryzen 7 5800XT, which claims 8 of the 11 head-to-head wins against the AMD Ryzen AI Embedded P164. The largest margin comes in the prime number search test, where the 5800XT scores 119 against the P164's 71, a 67.6% advantage. This is a substantial gap and indicates a significant difference in how the two processors handle this particular integer workload.

The 5800XT also dominates in data encryption, posting 21,461 versus 16,055, a 33.7% lead. The physics test shows a 12% advantage for the 5800XT (1,355 vs 1,210), and the multithread benchmark confirms the pattern with an 8.4% edge (28,053 vs 25,889). Smaller but consistent wins appear in integer math (93,942 vs 87,940, up 6.8%), data compression (352,002 vs 327,891, up 7.4%), random string sorting (35,911 vs 34,801, up 3.2%), and extended instructions (24,270 vs 24,193, up 0.3%).

The P164 fights back in three tests, most notably in single-thread performance. It scores 4,029 in the PassMark single-thread test versus the 5800XT's 3,535, a 12.3% advantage. This is a decisive win in a workload category that often matters for responsiveness and lightly threaded applications. The P164 also leads in floating-point math, posting 55,799 against 53,808, a 3.6% margin. The third win is essentially a repeat: the single-thread test appears twice in the database under slightly different names, and the P164 wins both by the same 12.3% delta.

Looking at the average benchmark scores, the P164 sits in a higher overall performance tier. Its average benchmark score is 52,901, while the 5800XT records 29,879. The percentile rankings confirm this: the P164 is in the 91st percentile among all CPUs, while the 5800XT sits in the 81st percentile. The nearest rival data for the P164 includes the AMD Ryzen 9 7900X at 53,288 (a 0.7% gap) and the AMD EPYC 7313P at 53,206, which places the P164 in strong company despite its mobile/embedded positioning. The 5800XT's nearest rivals are the AMD Ryzen 7 7840HS and 8845HS at 29,955 (0.3% higher) and the AMD Ryzen 7 7840H at 29,868, showing it clusters with high-end mobile parts from an older generation.

Architecture Differences

The two processors come from different architectural eras and serve different physical configurations. The AMD Ryzen 7 5800XT is built on Zen 3 (Vermeer) using a 7 nm TSMC process. It packs 8 cores and 16 threads with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The thermal design power is 105 watts, and it uses the AMD Socket AM4 platform. The die size is 74 mm² with 4,150 million transistors. Cache is organized as 64 KB of L1 per core, 512 KB of L2 per core, and a shared 32 MB L3 cache.

The AMD Ryzen AI Embedded P164 is a newer design, using the Gorgon Point codename with a hybrid Zen 5 / Zen 5c generation. It is manufactured on a 4 nm TSMC process and uses the AMD Socket FP8 (mobile platform). It also has 8 cores and 16 threads, but the base clock is much lower at 2.00 GHz, while the boost clock is higher at 5.00 GHz. The thermal design power is dramatically lower at 28 watts. The die is larger at 233 mm². Cache differs substantially: 80 KB of L1 per core, 1 MB of L2 per core, and only 8 MB of shared L3.

Memory support is a major differentiator. The 5800XT uses DDR4 with dual-channel bus and a recorded memory bandwidth of 51.2 GB/s. The P164 supports DDR5 and LPDDR5X, still dual-channel, but with a much higher memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity is similar in generation but different in lane count: the 5800XT offers Gen 4 with 20 CPU lanes, while the P164 offers Gen 4 with 16 CPU lanes.

The integrated graphics situation is stark. The 5800XT has no integrated graphics (N/A), requiring a discrete GPU. The P164 includes Radeon 880M graphics, which is a functional iGPU for display output and basic acceleration. The 5800XT has an unlocked multiplier, while the P164 does not. The 5800XT launched with a recorded MSRP of $249 and is a desktop part; the P164 is a mobile/embedded part with a production status of Active, released later per the database dates.

The transistor count is not recorded for the P164, and the 5800XT does not list a vCache option. The P164's lower base clock and higher boost clock, combined with a 28 W TDP, point to a design that aggressively boosts for short bursts but manages thermals tightly. The 5800XT, with a 105 W TDP and a steady 3.80 GHz base, is built for sustained desktop workloads.

The Verdict

The data separates these two processors cleanly by workload type. The AMD Ryzen 7 5800XT wins the majority of the head-to-head comparisons, particularly in multithreaded, integer-heavy, and encryption tasks. Its 67.6% lead in prime number searching and 33.7% lead in encryption are the largest margins in the dataset. For users running sustained parallel workloads, compression, sorting, or physics simulations, the 5800XT is the stronger choice according to the benchmark results.

The AMD Ryzen AI Embedded P164 is the single-thread champion, with a 12.3% advantage in the PassMark single-thread test. It also leads in floating-point math. Its higher average benchmark score (52,901 vs 29,879) and 91st percentile ranking indicate that, across the entire database of recorded scores, the P164 sits in a higher performance class. The nearest rival list for the P164 includes the AMD Ryzen 9 7900X, a high-end desktop part, which is a strong indicator of overall capability.

The architecture differences explain the split. The P164's Zen 5 / Zen 5c hybrid design with a 5.00 GHz boost clock delivers superior single-thread performance. The 5800XT's Zen 3 design with a lower boost clock but higher base clock and much larger 32 MB L3 cache excels in multithreaded and cache-sensitive workloads. The P164's 8 MB L3 is small by comparison, which likely contributes to its losses in data compression and integer math.

The thermal envelope is decisive for deployment scenarios. The P164 at 28 W is a low-power part suitable for embedded or mobile systems, while the 5800XT at 105 W is a desktop processor. The P164 includes integrated Radeon 880M graphics, while the 5800XT requires a discrete GPU. The 5800XT supports DDR4 and has 20 PCIe Gen 4 lanes; the P164 supports newer DDR5/LPDDR5X with higher bandwidth but fewer PCIe lanes. Platform choice comes down to whether the workload prioritizes single-thread speed with low power and integrated graphics, or multithreaded throughput with a larger cache and unlocked overclocking.

Where Each One Wins

The AMD Ryzen 7 5800XT wins in workloads that stress sustained multithreading and integer operations. The 67.6% lead in prime number searching makes it the clear pick for number-crunching tasks that involve primality testing or similar integer loops. The 33.7% lead in data encryption means the 5800XT handles cryptographic workloads with notably higher throughput. Integer math (6.8% ahead), multithread (8.4% ahead), and physics (12% ahead) all favor the 5800XT. Data compression is also a win at 7.4%, and random string sorting at 3.2% adds to the list. The 0.3% edge in extended instructions is marginal but still in the 5800XT's favor.

The AMD Ryzen AI Embedded P164 wins in single-thread performance and floating-point math. The 12.3% single-thread advantage is the strongest argument for the P164 in interactive or lightly threaded applications. The 3.6% lead in floating-point math suggests better performance in scientific or graphics-related calculations that rely on FPU throughput. The P164's higher average benchmark score and 91st percentile ranking indicate that, across the entire database, it competes with much higher-tier processors, including the AMD Ryzen 9 7900X and AMD EPYC 7313P.

For deployment decisions, the data points to the 5800XT for desktop builds where power draw is not a constraint and where multithreaded integer work dominates. The unlocked multiplier is an additional consideration for overclocking, though no overclocking benchmark data is recorded. The P164 suits embedded or mobile scenarios where the 28 W TDP and integrated Radeon 880M graphics matter, and where single-thread speed and floating-point capability are priorities. The P164's support for DDR5 and LPDDR5X with 89.6 GB/s bandwidth also gives it a memory subsystem advantage that the 5800XT cannot match.
