AMD Ryzen 3 5305GE vs Intel Core Ultra 5 338H Comparison

Where Each One Wins

The recorded data splits these two processors cleanly by intended environment. The AMD Ryzen 3 5305GE is a desktop part, built for Socket AM4 systems with a 35 W TDP, while the Intel Core Ultra 5 338H is a mobile processor in a BGA 2540 package with a 25 W TDP. That distinction alone shapes where each part can be deployed, but the benchmark results show the Intel chip winning every recorded workload comparison.

The Intel Core Ultra 5 338H posts a benchmark suite that covers Cinebench R15, R20, and R23 in both single-core and multi-core variants, plus PassMark tests for integer math, floating point math, encryption, compression, physics, prime number finding, random string sorting, extended instructions, and multithreaded performance. The AMD Ryzen 3 5305GE has no recorded benchmark scores in the database, so the wins column belongs entirely to the Intel part across all measured categories.

For productivity tasks that rely on multi-threaded rendering, the Intel chip delivers a Cinebench R23 multi-core score of 16331, which places it in the 84th percentile of all CPUs in the database. The AMD part sits at the 50th percentile with an average benchmark score of zero in the database, indicating no measured performance data exists for direct comparison. For single-threaded responsiveness, the Intel chip scores 2044 in Cinebench R23 single-core and 4180 in PassMark single-thread, figures that represent its strong per-core efficiency.

The Intel part also shows strength in data compression with a PassMark score of 276539, encryption at 21367, and floating point math at 84067. These numbers indicate a processor suited for workloads involving large data sets, cryptographic operations, and scientific calculations. The AMD Ryzen 3 5305GE, with its 4 cores and 8 threads, targets basic desktop usage where the absence of recorded benchmarks suggests it serves as an entry-level option, though the database cannot confirm its relative standing without scores.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 5305GE uses the Zen 3 architecture under the Cezanne codename, manufactured on a 7 nm process at TSMC. It packs 10,700 million transistors into a 180 mm² die. The Intel Core Ultra 5 338H uses the Panther Lake architecture, built on a 3 nm process at Intel's own foundry, with no transistor count or die size recorded in the database.

Cache hierarchies diverge sharply. The AMD part provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 8 MB of shared L3 cache. The Intel chip offers 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. That larger L3 pool gives the Intel processor a substantial advantage in workloads where frequently accessed data can stay on-die.

Memory support also differs. The AMD Ryzen 3 5305GE uses DDR4 memory in a dual-channel configuration, delivering 51.2 GB/s of bandwidth. The Intel Core Ultra 5 338H uses LPDDR5X in dual-channel mode, achieving 136.5 GB/s of bandwidth. That 2.67x bandwidth advantage matters for memory-intensive applications like video editing, large spreadsheet operations, or data processing tasks.

PCIe connectivity shows a generational gap. The AMD part provides PCIe Gen 3 with 16 lanes from the CPU, while the Intel chip offers PCIe Gen 5 with 4 lanes. The newer standard allows for much faster peripheral data transfer, though the lane count difference means the AMD part can connect more devices simultaneously at older speeds.

Integrated graphics also differ. The AMD Ryzen 3 5305GE includes Radeon Vega 6 graphics, while the Intel Core Ultra 5 338H carries Arc B370. Both are capable of driving displays without a discrete GPU, but the Intel solution belongs to a newer graphics generation.

Head-to-Head Benchmarks

Direct comparison is limited because the AMD Ryzen 3 5305GE has no recorded benchmark scores in the database. The Intel Core Ultra 5 338H, however, provides a full suite of results that define its performance envelope.

In Cinebench R23, the Intel chip scores 16331 multi-core and 2044 single-core. These numbers place it in the 84th percentile of all CPUs, with an average benchmark score of 33989. Its nearest rivals in the database include the Intel Core Ultra 7 165H with an average score of 34083, a 0.3% delta, and the Intel Core i7-12800HX at 33875, also a 0.3% delta. The Intel Xeon 6353P trails at 33844, a 0.4% delta, while the AMD EPYC 4244P leads at 34220, a 0.7% delta. This clustering indicates the Core Ultra 5 338H sits in a tight performance band around the 34000 mark.

In Cinebench R20, the Intel chip scores 10213 multi-core and 1441 single-core. The R15 results show 2504 multi-core and 305 single-core. These progressively lower scores across R15, R20, and R23 reflect the increasing computational demands of each benchmark version, not a decline in performance.

PassMark results reveal specific strengths. Integer math scores 64934, floating point math reaches 84067, and extended instructions hit 23906. Data compression reaches 276539, while encryption posts 21367. The multithread score sits at 28717, physics at 2697, and random string sorting at 34082. Prime number finding scores 304, a relatively modest figure that indicates this workload does not favor the chip's architecture.

The data shows a processor that excels at parallel throughput tasks. The 12 cores and 12 threads, combined with the 18 MB L3 cache and 136.5 GB/s memory bandwidth, create a platform capable of sustaining heavy multi-threaded loads. Single-thread performance, while not the class leader, still delivers competitive scores that keep everyday responsiveness snappy.

The clock speed relationship is interesting. The AMD part runs a higher base clock at 3.60 GHz versus 1.90 GHz, but the Intel chip boosts higher at 4.70 GHz versus 4.20 GHz. This suggests the Intel processor relies more on boost behavior under load, while the AMD chip maintains a steadier baseline frequency.

The transistor count for the AMD part is 10,700 million on a 180 mm² die. Intel does not disclose transistor or die size data in the database. The AMD chip uses an unlocked multiplier for overclocking, while the Intel part does not offer that flexibility.

Both processors lack ECC memory support and have no 3D V-Cache option. Both are actively produced, with the AMD part releasing in February 2025 and the Intel part in January 2026.
