AMD Ryzen 7 5705G vs Intel Core Ultra 5 338H Comparison

# AMD Ryzen 7 5705G vs Intel Core Ultra 5 338H

The database places the AMD Ryzen 7 5705G at the 50th percentile among all CPUs, while the Intel Core Ultra 5 338H sits at the 84th percentile. The Intel part also has a recorded average benchmark score of 33,989, whereas the AMD processor shows no recorded average score in the database. This percentile gap indicates a substantial overall performance difference, but the data also reveals clear workload-specific strengths for the desktop-oriented AMD chip.

Where Each One Wins

The Intel Core Ultra 5 338H dominates the recorded benchmark suite across nearly every category. In Cinebench R23 multi-core, the Intel processor scores 16,331 points, while Cinebench R20 multi-core shows 10,213 and Cinebench R15 multi-core shows 2,504. Single-core results follow the same pattern: 2,044 in Cinebench R23, 1,441 in R20, and 305 in R15. PassMark single-thread testing records 4,180 for the Intel chip, and its PassMark multithread score reaches 28,717. Data compression in PassMark produces 276,539, floating-point math reaches 84,067, integer math hits 64,934, and random string sorting lands at 34,082. Physics testing records 2,697, extended instructions score 23,906, and data encryption reaches 21,367. Even prime number finding, a workload that often favors high-frequency desktop chips, records 304 for the Intel part.

The AMD Ryzen 7 5705G has no individual benchmark scores in the database, so its wins cannot be quantified from recorded measurements. The data instead shows structural advantages. The AMD chip offers 8 cores and 16 threads, which is a 16-thread processing capability against the Intel chip's 12 threads. The AMD base clock of 3.80 GHz substantially exceeds the Intel base clock of 1.90 GHz, and the AMD boost clock of 4.60 GHz sits close to the Intel boost of 4.70 GHz. The AMD processor uses a 65 W TDP with an unlocked multiplier, while the Intel part is locked and rated at 25 W. These figures indicate that the AMD chip can sustain higher operating frequencies and supports manual overclocking, which benefits workloads that scale with clock speed rather than core count.

The Intel chip wins on memory bandwidth, recording 136.5 GB/s against the AMD chip's 51.2 GB/s, a difference that favors memory-intensive tasks. The Intel processor also supports PCIe Gen 5 with 4 CPU lanes, whereas the AMD chip uses PCIe Gen 3 with 16 CPU lanes. For workloads that depend on raw throughput per pin, the Intel design has the advantage, though the AMD platform provides more physical lanes.

Architecture Differences

The two processors come from different architectures, manufacturing nodes, and market segments. The AMD Ryzen 7 5705G uses Zen 3 architecture under the codename Cezanne, built on a 7 nm process at TSMC. It contains 10,700 million transistors on a 180 mm² die. The Intel Core Ultra 5 338H uses Panther Lake architecture, also its codename, built on Intel's 3 nm process. The Intel chip has no recorded transistor count or die size in the database.

Core and thread counts differ significantly. The AMD processor provides 8 cores and 16 threads, while the Intel processor provides 12 cores and 12 threads. The Intel chip has more physical cores but no hyperthreading, resulting in fewer total threads. Cache layouts also differ. The AMD chip uses 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. The Intel chip uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel L3 is larger in total capacity, and its per-core L1 and L2 allocations are substantially larger.

Clock behavior shows a clear split. The AMD base clock of 3.80 GHz is exactly double the Intel base clock of 1.90 GHz. The boost clocks are much closer: 4.60 GHz for AMD and 4.70 GHz for Intel. The Intel chip therefore relies on aggressive boosting to reach performance, while the AMD chip maintains higher frequencies at idle and under light load. The AMD processor is unlocked, allowing manual multiplier adjustment, while the Intel processor is locked.

Memory support differs by generation. The AMD chip uses DDR4 with dual-channel configuration, while the Intel chip uses LPDDR5X with dual-channel configuration. The measured memory bandwidth reflects this: 51.2 GB/s for AMD versus 136.5 GB/s for Intel. Neither processor supports ECC memory. The integrated graphics also differ, with the AMD chip featuring Radeon Graphics 512SP and the Intel chip featuring Arc B370.

The market segments and sockets reflect their intended use. The AMD processor is a desktop part for AMD Socket AM4, released on 2025-02-23. The Intel processor is a mobile part for Intel BGA 2540, released on 2026-01-04. The AMD chip belongs to the 5000 series, while the Intel chip belongs to Core Ultra Series 3. The production status for both is listed as Active.

The Verdict

The recorded data shows the Intel Core Ultra 5 338H as the clear performance leader in every benchmark category where measurements exist. Its average benchmark score of 33,989 places it at the 84th percentile, and its nearest rivals in the database include the Intel Core Ultra 7 165H at 34,083 (0.3% ahead), the Intel Core i7-12800HX at 33,875 (0.3% behind), the Intel Xeon 6353P at 33,844 (0.4% behind), and the AMD EPYC 4244P at 34,220 (0.7% ahead). These deltas show the Intel Core Ultra 5 338H competing closely with higher-tier workstation and mobile processors, which confirms strong multi-core and single-core performance.

The AMD Ryzen 7 5705G has no recorded benchmark scores or nearest rivals in the database, so its measured performance cannot be compared directly. Its 50th percentile ranking indicates it sits near the middle of all CPUs in the database. The AMD chip offers 16 threads, a higher base clock, an unlocked multiplier, and a desktop socket, which makes it suitable for users who prioritize overclocking, upgradeability on AM4, and sustained frequency in lightly threaded workloads. The Intel chip delivers higher memory bandwidth, more physical cores, and a more advanced manufacturing node, which supports memory-bound and multi-core tasks.

For a user selecting between these two, the data favors the Intel part for overall performance and efficiency, given its 25 W TDP and higher percentile ranking. The AMD part remains relevant for desktop builders who want an unlocked processor on an established socket with a higher base clock. The 65 W TDP of the AMD chip is higher than the Intel chip's 25 W TDP, which reflects the desktop versus mobile design split.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two processors, but the Intel Core Ultra 5 338H has 17 recorded individual test scores, while the AMD Ryzen 7 5705G has none. This asymmetry means every direct comparison relies on the Intel chip's recorded results.

In Cinebench R23 multi-core, the Intel chip scores 16,331, and its single-core score is 2,044. Cinebench R20 multi-core records 10,213, with a single-core score of 1,441. Cinebench R15 multi-core records 2,504, and single-core scores 305. These results indicate strong scaling from R15 to R23, with the multi-core score increasing by roughly 6.5 times from R15 to R23, consistent with the 12 cores and 12 threads.

PassMark results for the Intel chip show a multithread score of 28,717 and a single-thread score of 4,180. The data compression score of 276,539 is the highest recorded value among the PassMark tests, while floating-point math reaches 84,067 and integer math reaches 64,934. Random string sorting records 34,082, extended instructions record 23,906, and data encryption records 21,367. Physics testing records 2,697, and prime number finding records 304.

These numbers place the Intel Core Ultra 5 338H close to the Intel Core Ultra 7 165H, which has an average score of 34,083 and a delta of -0.3% relative to the 338H. The Intel Core i7-12800HX sits at 33,875 with a delta of 0.3%, meaning the 338H is roughly 0.3% ahead of that part in average score. The AMD EPYC 4244P is 0.7% ahead at 34,220, and the Intel Xeon 6353P is 0.4% behind at 33,844. Within this rival group, the 338H sits in the middle, nearly matching a higher-tier Ultra 7 part and a workstation EPYC processor.

For the AMD Ryzen 7 5705G, the lack of recorded scores means the database cannot confirm any workload where it beats the Intel chip. Its higher base clock of 3.80 GHz and 16 threads suggest potential advantages in latency-sensitive single-threaded tasks and heavily threaded workloads that use more than 12 threads, but no measured data supports these claims. The Intel chip's 136.5 GB/s memory bandwidth and 18 MB shared L3 cache provide the recorded hardware foundation for its strong PassMark and Cinebench results, while the AMD chip's 51.2 GB/s bandwidth and 16 MB L3 cache indicate a narrower memory pipeline. The recorded data consistently favors the Intel Core Ultra 5 338H.
