AMD Ryzen 7 PRO 5755GE vs Intel Core Ultra 5 135H Comparison

Head-to-Head Benchmarks

The benchmark data splits these two processors almost evenly, with the Intel Core Ultra 5 135H taking 9 of 17 head-to-head tests and the AMD Ryzen 7 PRO 5755GE taking 8. However, the margins tell a much more interesting story than the win count. The AMD part wins by large double-digit margins in several Cinebench tests, while the Intel part's victories are mostly narrow or moderate.

The single largest delta in the entire comparison belongs to the AMD Ryzen 7 PRO 5755GE in Cinebench R23 multicore, where it scores 17,759 against Intel's 11,875.5, a 49.5% advantage. The R23 single-core test shows a similar pattern: AMD scores 2,507 versus Intel's 1,700, a 47.5% lead. These are not subtle differences; they represent a generational gap in the recorded data for that workload.

Cinebench R15 also favors AMD, though by much smaller margins. The multicore result is 1,789 for AMD versus 1,718 for Intel, a 4.1% edge. Single-core R15 is 252 versus 244, a 3.3% advantage. In Cinebench R20, the tables turn. Intel takes multicore with 7,834 against AMD's 7,458, a 4.8% lead, and single-core with 1,105 versus 1,052, also 4.8% ahead.

PassMark results are split across different workload types. AMD wins data encryption with 16,937 versus 15,026, a 12.7% margin. Extended instructions go to AMD at 17,029 versus 15,028, a 13.3% lead. Integer math strongly favors AMD: 84,004 versus 73,509, a 14.3% advantage. Data compression is nearly tied, with AMD at 252,937 and Intel at 251,651, only 0.5% apart.

Intel's PassMark wins include floating point math at 54,867 versus 46,589, a 15.1% margin. Find prime numbers shows Intel at 89 versus AMD's 50, a massive 43.8% lead. Physics testing also goes decisively to Intel: 1,482 versus 841, a 43.3% edge. Multithread scores favor Intel at 22,422 versus 20,870, a 6.9% margin. Random string sorting goes to Intel at 28,980 versus 27,373, a 5.5% lead. Single-thread performance favors Intel at 3,521 versus 3,353, a 4.8% edge.

The overall average benchmark scores are close: AMD sits at 29,656 and Intel at 29,093. Both processors land in the 81st percentile of all CPUs in the database. AMD's nearest rival is the AMD Ryzen 5 9600X at 29,713, a 0.2% delta. Intel's nearest rival is the AMD Ryzen 7 5800X at 29,123, a 0.1% delta. The data indicates these two chips belong to the same performance tier overall, with workload-specific strengths and weaknesses.

Architecture Differences

The AMD Ryzen 7 PRO 5755GE uses the Zen 3 architecture on the Cezanne codename, built on a 7 nm process at TSMC. It packs 8 cores and 16 threads. The Intel Core Ultra 5 135H uses the Meteor Lake architecture, also on a 7 nm process but at Intel's own foundry. It contains 14 cores and 18 threads, reflecting a hybrid design approach.

Cache configurations differ significantly. AMD provides 64 KB of L1 per core and 512 KB of L2 per core, with 16 MB of shared L3. Intel provides 112 KB of L1 per core and 2 MB of L2 per core, with 18 MB of shared L3. The larger per-core L1 and L2 on the Intel side may contribute to its strong floating point and physics results.

Memory support diverges completely. AMD supports DDR4 with dual-channel access and 51.2 GB/s bandwidth. Intel supports DDR5 (dependent on motherboard) with dual-channel access and 89.6 GB/s bandwidth. The bandwidth difference is substantial and likely influences the Intel part's performance in memory-sensitive workloads.

PCIe generations differ as well. AMD offers Gen 3 with 16 lanes from the CPU. Intel offers Gen 5 with 8 lanes from the CPU. The newer PCIe standard on Intel provides higher potential bandwidth for attached devices, though lane count is lower.

Integrated graphics take different approaches. AMD integrates Radeon Vega 8 graphics. Intel integrates Arc Xe-LPG with 96 execution units. The Intel iGPU is a more modern design and likely offers better media and compute features, though the data does not include graphics benchmarks.

The AMD part is a desktop processor on Socket AM4. The Intel part is a mobile processor on BGA 2049. This fundamental difference affects where each can be installed. AMD has a 35W TDP, while Intel has a 28W TDP. Both are active production parts. AMD released in September 2024, while Intel released in December 2023.

Neither processor has an unlocked multiplier. AMD's transistor count is listed at 10,700 million with a die size of 180 mm²; Intel's transistor count and die size are not recorded in the database.

The Verdict

The data points to two different philosophies. The AMD Ryzen 7 PRO 5755GE is a desktop chip with fewer cores but very strong Cinebench results, particularly in R23 where it leads by nearly 50% in both single and multicore tests. The Intel Core Ultra 5 135H is a mobile chip with more cores and threads, higher base clock, faster memory bandwidth, and a clear advantage in physics, prime number finding, and floating point math.

For heavily threaded rendering workloads as measured by Cinebench R23, AMD is the clear choice. The 49.5% multicore lead and 47.5% single-core lead are decisive. For physics simulation, prime number computation, and floating point operations, Intel takes the lead with margins above 15% in those areas.

The overall average scores are close enough that neither processor dominates the other in general-purpose use. AMD's 29,656 average versus Intel's 29,093 is a 1.9% difference. Both chips sit at the same percentile ranking. The nearest rivals for each confirm they occupy the same performance class: AMD's closest competitor is the Ryzen 5 9600X at 29,713, and Intel's is the Ryzen 7 5800X at 29,123.

The Intel part carries a recorded launch MSRP of $342. The AMD part has no recorded launch MSRP in the database.

Where Each One Wins

Choose the AMD Ryzen 7 PRO 5755GE for Cinebench-style rendering and encoding workloads. Its R23 multicore score of 17,759 versus 11,875.5 is the largest gap in the entire comparison. It also wins integer math by 14.3%, data encryption by 12.7%, and extended instructions by 13.3%. If your work involves integer-heavy computation, encryption, or instruction-level extensions, AMD is the stronger pick.

Choose the Intel Core Ultra 5 135H for physics simulation, prime number finding, and floating point math. Its physics score of 1,482 versus 841 is a 43.3% advantage. The floating point math win at 54,867 versus 46,589 is a 15.1% margin. It also takes multithread workloads by 6.9% and single-thread PassMark by 4.8%. The higher memory bandwidth of 89.6 GB/s versus 51.2 GB/s may benefit memory-intensive tasks, though the recorded benchmarks do not isolate that variable directly.

For general productivity with mixed workloads, the data shows a near tie. The average benchmark scores are within 2% of each other. The Intel part has more cores and threads, which may help in lightly threaded or highly parallel scenarios that the recorded tests do not fully capture. The AMD part has a desktop socket and a 35W TDP, suggesting it belongs in a stationary system, while the Intel part is designed for mobile platforms with a 28W TDP.

The final call depends on the specific workload. If the application resembles Cinebench R23, take AMD. If it resembles physics or floating point math tests, take Intel. The recorded data does not support a universal winner, only a workload-dependent one.
