AMD Ryzen 7 PRO 5875U vs Intel Xeon D-2733NT Comparison

The Intel Xeon D-2733NT and AMD Ryzen 7 PRO 5875U are both 8-core, 16-thread processors, but they target entirely different segments: the former is a server/workstation chip, while the latter is a mobile part. Despite this, their average benchmark scores are nearly identical, with the AMD chip edging ahead across every single Cinebench test in the head-to-head comparison. The data reveals a surprisingly close contest between a low-power mobile processor and a server-oriented Xeon, with the Ryzen 7 PRO 5875U winning all six head-to-head matchups, albeit by narrow margins.

Head-to-Head Benchmarks

The benchmark results consistently favor the AMD Ryzen 7 PRO 5875U, though the margins are slim. In Cinebench R15, the AMD chip scores 1421 in multi-core versus 1388 for the Intel Xeon D-2733NT, a delta of -2.3% from the perspective of the Intel part. The single-core R15 result follows the same pattern: AMD scores 200 against Intel's 195, a 2.5% gap. Moving to Cinebench R20, the AMD processor again leads in multi-core with 5922 points over Intel's 5785, and in single-core with 835 versus 816. Both differences hover around the 2.3% mark.

The trend continues in Cinebench R23, where the AMD Ryzen 7 PRO 5875U achieves 14102 multi-core points versus Intel's 13775, and 1990 single-core points versus 1944. Again, the delta sits at -2.3%. The widest relative gap appears in the R15 single-core test at 2.5%, while all other multi-core and single-core deltas are consistently 2.3%. This uniformity suggests that the AMD chip's advantage comes from a fundamental architectural efficiency rather than a workload-specific edge.

It is notably the Intel Xeon D-2733NT holds zero wins across the six head-to-head benchmarks, while AMD takes all six. However, the average benchmark scores tell a slightly different story: Intel's average is 3984, and AMD's is 3971. This places the AMD part within 0.3% of the Intel chip in overall average, according to the Intel Xeon's nearest rivals list, which includes the AMD Ryzen 7 PRO 5875U with a deltaPct of 0.3. Interestingly, the AMD part's own nearest rivals list shows the Intel Xeon E5-2669 v3 at 0.3% behind, but the Xeon D-2733NT does not appear there, suggesting the average score comparison is close but not perfectly reciprocal.

It features 8 cores and 16 threads with a base clock of 2.10 GHz and a boost of 3.20 GHz. The cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 15 MB of shared L3. Memory support is DDR4 over a quad-channel bus, delivering 85.3 GB/s of bandwidth, and it supports ECC memory. The chip uses an Intel BGA 2579 socket and offers PCIe Gen 4 with 32 lanes from the CPU. Its market segment is explicitly Server/Workstation, and it was released on 2022-02-23.

In contrast, the AMD Ryzen 7 PRO 5875U is a Zen 3 mobile part, codenamed Cezanne-U, fabricated on a 7 nm process by TSMC. It also has 8 cores and 16 threads, but with a base clock of 2.00 GHz and a much higher boost of 4.50 GHz. Its cache structure is different: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Memory is DDR4 over a dual-channel bus, providing 51.2 GB/s, and it does not support ECC. The socket is AMD Socket FP6, and PCIe support is limited to Gen 3 with 8 lanes. It includes integrated Radeon Vega 8 graphics. The chip is classified as a Mobile processor, released on 2022-04-18, and has a documented transistor count of 10,700 million on a 180 mm² die.

The process node difference is a key differentiator: the 7 nm TSMC process versus Intel's 10 nm. This contributes to the AMD chip's ability to achieve a 4.50 GHz boost clock at a 15 W TDP, whereas the Intel chip, with an 80 W TDP, tops out at 3.20 GHz. The Intel part compensates with quad-channel memory and ECC support, which are server-grade features absent from the mobile AMD chip.
