AMD Ryzen 7 5705G vs Intel Core Ultra 3 205 Comparison

Where Each One Wins

The recorded data splits cleanly between the two processors. The AMD Ryzen 7 5705G has no individual benchmark entries in the database, so its competitive position must be inferred from its architectural profile, while the Intel Core Ultra 3 205 carries a full suite of measured scores. The Intel part dominates the measured workload set, with every recorded benchmark belonging to it. That includes Cinebench R15, R20, and R23 runs for both multi-core and single-core, plus PassMark tests for integer math, floating point math, data compression, data encryption, extended instructions, prime number search, random string sorting, physics, and multithreaded throughput.

The AMD Ryzen 7 5705G holds advantages in structural terms rather than in recorded scores. It offers 16 threads against the Intel chip's 8 threads, which matters for heavily threaded workloads, and its 65W TDP sits above the Intel part's 57W, suggesting a different power envelope. The AMD chip also includes Radeon Graphics with 512 shader processors, compared to the Intel Arc Xe-LPG Graphics with 16 execution units, indicating a substantially different integrated graphics capability. The Intel Core Ultra 3 205 reaches a higher boost clock of 4.90 GHz versus 4.60 GHz, and its percentile ranking of 82 against all CPUs places it well above the AMD part's 50th percentile.

The use-case split is therefore defined by measured results versus architectural headroom. For any workload represented in the database, the Intel Core Ultra 3 205 delivers the score. For workloads that depend on simultaneous multithreading, the AMD Ryzen 7 5705G brings twice the thread count. The Intel chip belongs to the Core Ultra Series 2 family with a launch MSRP of $140, while the AMD chip uses the AM4 platform with DDR4 memory support, a mature socket ecosystem that favors upgrades from older systems.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 7 5705G uses Zen 3 architecture with the Cezanne codename, built on a 7 nm process at TSMC. The Intel Core Ultra 3 205 uses Arrow Lake architecture with the Arrow Lake-S codename, built on a 3 nm process, also at TSMC. The process node difference is substantial: 7 nm versus 3 nm, which influences transistor density and power characteristics. The AMD chip packs 10,700 million transistors on a 180 mm² die, while the Intel chip carries 17,800 million transistors on a 243 mm² die.

Core and cache layouts differ sharply. The AMD Ryzen 7 5705G has 8 cores and 16 threads with 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3. The Intel Core Ultra 3 205 also has 8 cores but only 8 threads, with 192 KB of L1 per core, 3 MB of L2 per core, and 15 MB of shared L3. The Intel part therefore has larger per-core L1 and L2 allocations, while the AMD part offers simultaneous multithreading and a slightly larger L3 pool.

Memory support splits by generation. The AMD chip uses DDR4 with dual-channel access and 51.2 GB/s of memory bandwidth. The Intel chip uses DDR5 with dual-channel access and 102.4 GB/s of memory bandwidth, exactly double the AMD figure. PCIe connectivity differs as well: the AMD Ryzen 7 5705G provides Gen 3 with 16 lanes from the CPU, while the Intel Core Ultra 3 205 provides Gen 5 with 20 lanes from the CPU. That gives the Intel platform substantially more I/O headroom for storage and expansion.

The integrated graphics solutions are in different classes. AMD pairs the Ryzen 7 5705G with Radeon Graphics rated at 512 shader processors. Intel pairs the Core Ultra 3 205 with Arc Xe-LPG Graphics rated at 16 execution units. The AMD solution likely favors general display output and light graphics duties, while the Intel Arc branding suggests a different feature set, but the database records no direct graphics benchmarks for either chip.

The Intel Core Ultra 3 205 has a locked multiplier, while the AMD Ryzen 7 5705G has an unlocked multiplier, allowing manual overclocking on the AMD side. Both processors lack ECC memory support. The Intel chip was released on 2025-07-31, while the AMD chip appeared on 2025-02-23. The AMD chip uses Socket AM4, the Intel chip uses Socket 1851, so platform choice is a deciding factor for any build.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen 7 5705G and the Intel Core Ultra 3 205. The winsA and winsB fields both read zero, and the headToHeadBenchmarks array is empty. All measured scores belong to the Intel part alone. The Intel Core Ultra 3 205 records a Cinebench R23 multi-core score of 19856 and a single-core score of 2803. In Cinebench R20, it posts 8339 multi-core and 1177 single-core. In Cinebench R15, it posts 2001 multi-core and 282 single-core.

PassMark results for the Intel chip include a multithread score of 26167, a single-thread score of 4575, integer math at 54755, floating point math at 75136, data compression at 260651, data encryption at 18772, extended instructions at 22578, prime number search at 268, random string sorting at 31083, and physics at 2016. The average benchmark score sits at 31473, with a percentile rank of 82 against all CPUs.

The nearest rivals for the Intel Core Ultra 3 205 put its performance in context. The Intel Core 7 240H averages 31483, a delta of 0 percent. The AMD Ryzen 9 5980HX averages 31495, a delta of -0.1 percent. The Intel Core Ultra 5 225H averages 31508, a delta of -0.1 percent. The Intel Core i5-13500 averages 31510, a delta of -0.1 percent. The Core Ultra 3 205 therefore sits within a hair of these four processors, trailing the fastest by only 0.1 percent. This places the Intel chip in the upper tier of desktop processors, just below the 240H, the 5980HX, the 225H, and the i5-13500.

The AMD Ryzen 7 5705G has no nearest rivals listed and no average benchmark score, so its numerical standing cannot be compared directly. Its 50th percentile ranking indicates a mid-pack position across all CPUs, well below the Intel chip's 82nd percentile. The absence of benchmark entries for the AMD part means every numeric comparison in this section relies on the Intel measurements alone.

The Verdict

The measured data favors the Intel Core Ultra 3 205 in almost every quantifiable dimension. Its 82nd percentile ranking versus the AMD chip's 50th percentile, its higher boost clock of 4.90 GHz, its double memory bandwidth at 102.4 GB/s, its smaller 3 nm process node, and its full suite of recorded benchmark scores all point to a stronger overall performer. The nearest rival data reinforces this: the Core Ultra 3 205 lands within 0.1 percent of the Core 7 240H, the Ryzen 9 5980HX, the Core Ultra 5 225H, and the Core i5-13500, all of which are established high-performance parts. The Cinebench R23 multi-core score of 19856 and single-core score of 2803 place it comfortably in the upper tier of desktop silicon.

The AMD Ryzen 7 5705G still claims specific advantages that the Intel chip cannot match. Its 16 threads versus 8 threads gives it a structural edge in heavily threaded scenarios, even without recorded scores to confirm the magnitude. Its unlocked multiplier permits overclocking, while the Intel multiplier is locked. Its Socket AM4 platform and DDR4 support cater to users upgrading existing systems rather than building new ones. The Radeon Graphics with 512 shader processors also present a different integrated graphics profile than the Intel Arc Xe-LPG with 16 execution units.

The database supports a clear split. Users prioritizing raw measured performance, modern memory bandwidth, PCIe Gen 5 connectivity, and a top-tier percentile ranking should select the Intel Core Ultra 3 205. Users prioritizing thread count, overclocking freedom, and an established AM4 platform with DDR4 compatibility should select the AMD Ryzen 7 5705G. The Intel chip delivers the recorded performance, while the AMD chip delivers the architectural flexibility.
