AMD Ryzen 7 PRO 5755G vs Intel Core Ultra 5 245 Comparison

The AMD Ryzen 7 PRO 5755G and Intel Core Ultra 5 245 are both active desktop processors that land in the 90th percentile of all CPUs, yet their benchmark profiles could hardly be more different. The data shows a clean sweep: the Intel Core Ultra 5 245 wins all 11 head-to-head benchmark comparisons, with margins ranging from a narrow 1% in integer math to a massive 84.1% in prime number finding. The average benchmark scores are nearly identical — the AMD chip scores 49,196 versus Intel's 48,995, a delta of just 0.4% — but that aggregate figure masks the reality that the Ryzen 7 PRO 5755G never wins a single listed test. The Intel part's advantage is broad and consistent, while the AMD chip's only consolation is that its 8-core, 16-thread configuration keeps the overall average competitive.

The Verdict

The benchmark data points to a straightforward conclusion: the Intel Core Ultra 5 245 is the superior performer in every measured workload, and the Ryzen 7 PRO 5755G should only be chosen when its specific platform characteristics are non-negotiable. For users who prioritize raw throughput — whether that is data compression, encryption, floating-point math, or multi-threaded rendering — the Intel part is the clear choice, with wins of 26.2%, 35.7%, 57.9%, and 38.4% respectively. The Intel chip also dominates single-threaded performance, scoring 4,394 versus the AMD's 3,366 in the PassMark single-thread test, a 23.4% gap that will matter for lightly-threaded applications. The Ryzen 7 PRO 5755G's sole argument is its older, established AM4 platform and DDR4 memory support, which the data does not quantify in performance terms but which may appeal to users with existing infrastructure. That said, the Intel Core Ultra 5 245's 14 cores (versus 8) and 5.10 GHz boost clock (versus 4.60 GHz) are the structural reasons for its dominance, and the benchmark results leave no room for a performance-based recommendation of the AMD part.

Where Each One Wins

Based strictly on the head-to-head results, the Intel Core Ultra 5 245 wins in every category where a comparison exists. The most extreme victory is in PassMark's find prime numbers test, where Intel scores 365 against AMD's 58 — an 84.1% lead that suggests a dramatic advantage in integer-heavy, single-threaded loops. The Intel part also excels in physics simulation, scoring 2,569 versus 1,022 (a 60.2% win), and in floating-point math, where it nearly doubles the AMD's output at 120,548 versus 50,778 (a 57.9% margin). For multi-threaded workloads, the PassMark multithread score of 38,706 versus 23,858 translates to a 38.4% advantage, and the Cinebench R23 multicore score of 32,924 (Intel) reinforces this pattern, though no equivalent AMD score is listed. The AMD Ryzen 7 PRO 5755G does not win any benchmark in the data, so its "win" is purely contextual: it is the only one of the two that supports DDR4 memory, and it uses the older AM4 socket, which may be an advantage for users upgrading existing systems. In terms of raw performance, however, there is no scenario in the provided benchmarks where the AMD chip comes out ahead.

Architecture Differences

The two processors represent fundamentally different design philosophies and generations. The AMD Ryzen 7 PRO 5755G is built on TSMC's 7 nm process with 10,700 million transistors on a 180 mm² die, using the Zen 3 architecture (codename Cezanne). It features 8 cores and 16 threads, a base clock of 3.80 GHz and boost of 4.60 GHz, with 64 KB of L1 cache per core, 512 KB of L2 per core, and a 16 MB L3 cache. It supports DDR4 memory over a dual-channel bus with a bandwidth of 51.2 GB/s, and its PCIe implementation is Gen 3 with 16 lanes from the CPU. The integrated graphics are Radeon Vega 8. In contrast, the Intel Core Ultra 5 245 is built on TSMC's 3 nm process with 17,800 million transistors on a 243 mm² die, using the Arrow Lake architecture (codename Arrow Lake-S). It has 14 cores and 14 threads — meaning no hyperthreading — with a base clock of 3.50 GHz and a boost of 5.10 GHz. Its cache hierarchy is markedly different: 192 KB of L1 per core, 3 MB of L2 per core, and a 24 MB shared L3 cache. It supports DDR5 memory with a dual-channel bus and a bandwidth of 102.4 GB/s, double the AMD part's, and includes PCIe Gen 5 with 20 lanes from the CPU. The Intel chip also supports ECC memory, while the AMD chip does not, and its integrated graphics are Arc Xe-LPG with 64 execution units. The process node difference alone — 3 nm versus 7 nm — explains much of the power and efficiency gap, and the Intel part's larger transistor count and die size reflect a more complex design.

Head-to-Head Benchmarks

The most lopsided result in the entire comparison is the PassMark find prime numbers test, where the Intel Core Ultra 5 245 scores 365 and the AMD Ryzen 7 PRO 5755G scores 58. This 84.1% margin suggests the Intel architecture handles integer iteration far more efficiently, likely due to its higher boost clock of 5.10 GHz versus 4.60 GHz and its newer 3 nm process. The floating-point math test shows a similarly decisive outcome: Intel's 120,548 against AMD's 50,778 is a 57.9% win, which aligns with the Intel part's larger L2 cache (3 MB per core versus 512 KB per core) and more modern vector execution units. The physics test also favors Intel heavily, with a score of 2,569 versus 1,022, a 60.2% difference that points to better handling of collision detection and rigid body dynamics. In data compression, Intel wins 400,942 to 295,730 (26.2%), and in data encryption, Intel wins 30,236 to 19,450 (35.7%), both showing the AMD chip is not merely slower but significantly behind in throughput-oriented tasks. The extended instructions test gives Intel a 33,304 to 20,487 win (38.5%), and random string sorting favors Intel at 49,140 versus 32,771 (33.3%). The closest contest is PassMark integer math, where Intel scores 91,187 and AMD scores 90,270 — a razor-thin 1% margin that shows the AMD chip is competitive on pure integer arithmetic but loses everywhere else. The multi-thread test (38,706 vs. 23,858, a 38.4% win for Intel) and the single-thread test (4,394 vs. 3,366, a 23.4% win) round out a comprehensive sweep. Notably, the AMD chip's PassMark multithread score of 23,858 is its only data point that approaches Intel's performance tier, yet it still falls short by a wide margin.

Specification Differences

The two processors diverge on nearly every core specification. The AMD Ryzen 7 PRO 5755G has 8 cores and 16 threads, while the Intel Core Ultra 5 245 has 14 cores and 14 threads. Base clocks are 3.80 GHz for AMD and 3.50 GHz for Intel, but boost clocks reverse the order: 4.60 GHz for AMD and 5.10 GHz for Intel. Both have a 65 W TDP. The AMD chip uses the AMD Socket AM4, while Intel uses Socket 1851. Architecture and codename differ: Zen 3 (Cezanne) versus Arrow Lake (Arrow Lake-S). The process node is 7 nm for AMD and 3 nm for Intel, with transistor counts of 10,700 million and 17,800 million respectively, and die sizes of 180 mm² and 243 mm². Cache configurations are distinct: AMD has 64 KB L1 per core, 512 KB L2 per core, and 16 MB L3; Intel has 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. Memory support differs entirely — DDR4 versus DDR5 — with bandwidths of 51.2 GB/s and 102.4 GB/s. ECC memory is not supported by AMD but is supported by Intel. PCIe versions are Gen 3 with 16 lanes for AMD and Gen 5 with 20 lanes for Intel. Integrated graphics are Radeon Vega 8 for AMD and Arc Xe-LPG Graphics 64EU for Intel.
