AMD Ryzen 5 5600GT vs Intel Core Ultra 7 155U Comparison

Head-to-Head Benchmarks

The benchmark data paints a clear picture of two processors with very different strengths. The AMD Ryzen 5 5600GT dominates in raw multi-threaded and most compute-heavy workloads, while the Intel Core Ultra 7 155U claims victory in a smaller but distinct set of tasks.

Starting with the most dramatic gap, Cinebench R23 multi-core results show the AMD Ryzen 5 5600GT scoring 17,272 against the Intel Core Ultra 7 155U's 9,674.5, a 44% advantage. This is the largest delta in the entire head-to-head set. The gap persists across the Cinebench suite: R20 multi-core shows a 20.5% lead for AMD (7,254 vs 5,765), and even R15 multi-core shows an 8.9% edge (1,740 vs 1,585). In single-threaded Cinebench tests, the AMD part also wins, though by smaller margins: 20.5% in R20 (1,023 vs 813) and 31.7% in R23 (2,438 vs 1,666). The R15 single-core result is closer at 2.7% (245 vs 238.5).

The AMD processor extends its lead into PassMark workloads. Data compression shows a 31.6% advantage (258,882 vs 177,122), data encryption a 28.6% edge (15,873 vs 11,333), and extended instructions a 45.1% gap (18,041 vs 9,903). Integer math also favors AMD at 17.3% (69,566 vs 57,564), as does random string sorting at 24.5% (26,188 vs 19,767). The PassMark multi-thread score confirms the trend: 20,325 for AMD versus 16,382 for Intel, a 19.4% difference.

However, the Intel Core Ultra 7 155U is not without its wins. The most notable is PassMark physics, where Intel scores 1,084 against AMD's 875, a 23.9% advantage. Prime number finding also goes to Intel (65 vs 57, a 14% lead), and floating point math is essentially a tie but technically Intel's at 1.1% (40,256 vs 39,817). In single-threaded PassMark tests, Intel edges out AMD by 0.7% (3,372 vs 3,348). Overall, the head-to-head tally shows AMD winning 12 of 17 benchmarks, with Intel taking 5.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Core Ultra 7 155U is built on the Meteor Lake architecture, fabricated by Intel on a 7 nm process. It uses a hybrid core layout with 12 cores and 14 threads, designed for mobile efficiency. The AMD Ryzen 5 5600GT, meanwhile, uses the Zen 3 architecture on the Cezanne codename, built by TSMC on a 7 nm process. It has 6 cores and 12 threads, a more traditional desktop configuration.

Cache structures differ markedly. The Intel part has 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. The AMD part has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. The AMD processor also carries a disclosed transistor count of 10,700 million and a die size of 180 mm², while the Intel processor has no transistor or die size figures recorded.

Memory support highlights a key platform split. The Intel Core Ultra 7 155U supports DDR5 with memory bandwidth of 89.6 GB/s, while the AMD Ryzen 5 5600GT supports DDR4 with 51.2 GB/s. Both use dual-channel memory buses and neither supports ECC. PCIe connectivity differs as well: Intel offers Gen 4 with 12 CPU lanes, while AMD offers Gen 3 with 16 CPU lanes.

Integrated graphics also diverge. Intel uses Arc Xe-LPG with 64 execution units, while AMD uses Radeon Vega 7. The market segments reflect their intended use: Intel is a mobile part, AMD is a desktop part. The Intel processor's TDP is 15 watts, while the AMD processor's TDP is 65 watts, which explains the performance differences in sustained workloads.

The Verdict

The data directs different users to different processors. If the priority is sustained multi-threaded throughput, the AMD Ryzen 5 5600GT is the clear choice. Its Cinebench R23 multi-core score is 44% higher, and it leads by double digits in most PassMark workloads including data compression, encryption, integer math, and random string sorting. The AMD part also wins every single-threaded Cinebench test, with margins from 2.7% to 31.7%.

The Intel Core Ultra 7 155U has a narrower but distinct profile. Its PassMark physics score is 23.9% higher, and it wins in prime number finding and floating point math. Single-threaded PassMark scores are essentially tied, with Intel ahead by 0.7%. The Intel part also carries a much lower TDP of 15 watts versus 65 watts, which reflects its mobile design and likely explains its different thermal and power behavior.

For a desktop build where performance per watt is less of a constraint, the AMD Ryzen 5 5600GT offers superior compute across most measured categories. For a mobile platform or a system where the lower TDP and higher memory bandwidth (89.6 GB/s vs 51.2 GB/s) matter, the Intel Core Ultra 7 155U has measurable advantages. The average benchmark scores are close, with Intel at 21,174 and AMD at 20,733, but the distribution of wins favors AMD in the majority of tests. The AMD part also has the higher boost clock at 4.60 GHz and an unlocked multiplier, while Intel boosts to 4.80 GHz but remains locked. The socket and platform differences are substantial: Intel uses BGA 2049 with DDR5, AMD uses AM4 with DDR4. The choice ultimately rests on whether the workload matches AMD's multi-threaded strengths or Intel's specific efficiency and physics-related wins.
