AMD Ryzen 7 PRO 5755G vs Intel Core 9 273PE Comparison

# Intel Core 9 273PE vs AMD Ryzen 7 PRO 5755G

The benchmark data is unambiguous: the Intel Core 9 273PE wins all 11 head-to-head comparisons against the AMD Ryzen 7 PRO 5755G, with victory margins ranging from a modest 8.4% in single-threaded workloads to a staggering 250% in prime number finding. The Intel part's average benchmark score of 49,845 places it 1.3% above its rival's 49,196 average, but the per-test deltas reveal a far more lopsided contest than that aggregate suggests. While both processors sit at the 90th percentile among all CPUs, the Intel Core 9 273PE is the clear performance leader across every measurable category in the data.

Head-to-Head Benchmarks

The largest single victory for the Intel Core 9 273PE comes in the PassMark find prime numbers test, where it scores 203 versus the AMD's 58 — a 250% advantage. This is not an isolated anomaly; the pattern of dominance repeats across compute-intensive workloads. In floating point math, Intel scores 107,884 against AMD's 50,778, a 112.5% lead. The physics test shows a 205.3% gap (3,120 vs 1,022), indicating that the Intel part handles complex physical simulations with more than triple the throughput.

Multi-threaded performance tells a similar story. The Intel Core 9 273PE achieves 36,810 in PassMark's multithread test, while the AMD Ryzen 7 PRO 5755G manages 23,858 — a 54.3% difference. Integer math follows closely with Intel at 139,410 versus AMD's 90,270, a 54.4% edge. The data compression test shows Intel at 405,885 compared to AMD's 295,730 (37.2% ahead), while random string sorting sees Intel win 45,098 to 32,771 (37.6%).

The closest contest is in single-threaded performance, where Intel's 3,650 score beats AMD's 3,366 by just 8.4%. This is still a decisive win, but it is the only benchmark where the two processors approach parity. Data encryption shows Intel ahead by 16.8% (22,719 vs 19,450), and extended instructions see Intel lead by 20.2% (24,630 vs 20,487). Across all 11 head-to-head tests, Intel wins every single one — there is no category where the AMD Ryzen 7 PRO 5755G takes the lead.

Architecture Differences

The Intel Core 9 273PE is built on a 10 nm process at Intel's foundry, codenamed Bartlett Lake, and belongs to the Core 9 generation. It packs 12 cores and 24 threads, with a base clock of 2.30 GHz boosting to 5.70 GHz. The cache hierarchy is generous: 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. It supports both DDR4 and DDR5 memory in a dual-channel configuration, delivering 89.6 GB/s of memory bandwidth. The chip also includes ECC memory support, PCIe Gen 5 with 16 lanes (CPU only), and integrated UHD Graphics 730.

The AMD Ryzen 7 PRO 5755G, in contrast, uses TSMC's 7 nm process and the Zen 3 architecture, codenamed Cezanne, from the 5000 series. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. The cache is smaller across the board: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. Memory support is limited to DDR4 in dual-channel, yielding 51.2 GB/s of bandwidth — 43% less than the Intel part. No ECC support is listed, and the AMD chip uses PCIe Gen 3 with 16 lanes. Its integrated graphics is Radeon Vega 8. The AMD chip also carries a transistor count of 10,700 million on a 180 mm² die, while the Intel part's transistor count and die size are not listed in the data.

These architectural differences explain the benchmark results. The Intel Core 9 273PE has 50% more cores (12 vs 8) and 50% more threads (24 vs 16), which directly drives its dominance in multi-threaded workloads like the multithread, integer math, and floating point tests. The higher boost clock (5.70 GHz vs 4.60 GHz) contributes to the single-threaded advantage, even though the AMD chip starts with a higher base clock (3.80 GHz vs 2.30 GHz). The larger L3 cache (36 MB vs 16 MB) and faster memory bandwidth (89.6 GB/s vs 51.2 GB/s) further widen the gap in memory-sensitive tasks like data compression and random string sorting.

The Verdict

The data points to a single conclusion: the Intel Core 9 273PE is the superior processor for virtually every workload measured. It wins 11 of 11 head-to-head benchmarks, with an average score of 49,845 compared to 49,196 for the AMD Ryzen 7 PRO 5755G. The Intel part's nearest rivals according to average score are the AMD Ryzen AI Max+ 388 (49,796, 0.1% difference) and the Intel Core i5-14600KF (49,394, 0.9% ahead), while the AMD Ryzen 7 PRO 5755G sits closest to the AMD Ryzen 9 7900 (49,228, 0.1% behind) and the Intel Core i5-14600KF (49,394, 0.4% behind). Both processors rank at the 90th percentile overall, but the Intel part's head-to-head sweep makes it the clear choice when performance is the sole criterion.

The AMD Ryzen 7 PRO 5755G is not without merit — its single-threaded score of 3,366 trails Intel by only 8.4%, and its 90th percentile ranking shows it is a capable processor in absolute terms. However, in every direct comparison, the Intel Core 9 273PE comes out ahead, often by substantial margins. The Intel chip's advantage is most pronounced in prime number finding (250%), physics (205.3%), and floating point math (112.5%), where the combination of more cores, higher clocks, and larger caches proves decisive.

Where Each One Wins

The Intel Core 9 273PE wins in every benchmark category included in the data, making the use-case split straightforward. For compute-intensive tasks such as prime number finding (250% faster), physics simulations (205.3% faster), and floating point math (112.5% faster), the Intel part is the overwhelming choice. Its 54.3% lead in multithread performance and 54.4% edge in integer math make it ideal for heavily parallel workloads like video rendering, scientific computing, and data analysis. The 37.2% advantage in data compression and 37.6% lead in random string sorting also position it well for database and file-management tasks. Even in single-threaded applications, where the gap narrows to 8.4%, the Intel Core 9 273PE still takes the win.

The AMD Ryzen 7 PRO 5755G, despite losing every head-to-head test, is not without application scenarios where it could be considered. Its 90th percentile ranking confirms it is a solid performer, and its single-threaded score of 3,366 is within 8.4% of the Intel part, meaning lightly threaded applications would show only a minor difference. The AMD chip's higher base clock of 3.80 GHz could provide more consistent performance in bursty, short-duration workloads, though the Intel part's 5.70 GHz boost clock negates this in sustained single-thread tasks. For users on an AMD Socket AM4 platform who already have compatible motherboards, the Ryzen 7 PRO 5755G offers a competitive upgrade path without changing platforms, but the raw performance data shows the Intel Core 9 273PE is the faster processor in every measured scenario.
