AMD Ryzen 7 4700U vs Intel Xeon D-1577 Comparison

The AMD Ryzen 7 4700U and Intel Xeon D-1577 represent two fundamentally different approaches to computing, one a low-power mobile processor and the other a server-focused system-on-chip. Despite their divergent designs, they land remarkably close in aggregate performance, with the AMD part posting an average benchmark score of 2722 against the Intel's 2715, a margin of just 0.2%. This parity makes the head-to-head benchmark results particularly revealing, as each chip claims victories in different workload types.

Head-to-Head Benchmarks

The most striking split emerges in Cinebench testing, where the two processors trade blows based on the render workload. In Cinebench R15 multi-core, the AMD Ryzen 7 4700U wins decisively with a score of 1094.5 against the Xeon D-1577's 946, a 15.7% advantage. The single-core R15 test shows an even larger gap, with the AMD part scoring 180 versus 133, a 35.3% lead that reflects the Ryzen's much higher boost clock. These results indicate that in older, less thread-scalable render workloads, the AMD chip's per-core efficiency dominates.

However, the picture flips dramatically in Cinebench R23. The Intel Xeon D-1577 takes the multi-core crown with a score of 9389 compared to the Ryzen's 7378, representing a 21.4% advantage for Intel. This reversal is explained by the Xeon's 16 cores and 32 threads, which allow it to scale far better in the more demanding R23 test. Even in R23 single-core, the Xeon edges out a win, scoring 1325 against the Ryzen's 1220.5, a 7.9% margin. This is notable because it shows the older Broadwell architecture still holds its own in certain single-threaded scenarios, despite its lower clock speeds.

The overall win tally sits at 2-2, but the magnitude of the victories differs. The AMD chip's R15 single-core win of 35.3% is its largest margin, while the Intel part's R23 multi-core victory of 21.4% is its most significant. When examining the broader benchmark suite, the Ryzen 7 4700U also holds advantages in Geekbench, scoring 5189 multi-core and 1268 single-core, though no direct head-to-head comparison is available for those tests. The average benchmark score of 2722 for the AMD part versus 2715 for the Intel part confirms these are closely matched processors overall.

Architecture Differences

The architectural divide between these two chips is substantial. The AMD Ryzen 7 4700U is built on TSMC's 7 nm process node, packing 9,800 million transistors into a 156 mm² die. It uses the Zen 2 architecture with the Renoir codename, representing the 4000 series generation. In contrast, the Intel Xeon D-1577 relies on Intel's 14 nm process, containing 3,200 million transistors across a larger 246 mm² die. This means the AMD chip achieves significantly higher transistor density, with roughly three times the transistors in a smaller area.

Core and thread configurations differ markedly. The Ryzen 7 4700U offers 8 cores and 8 threads, with no simultaneous multithreading, while the Xeon D-1577 provides 16 cores and 32 threads, using Hyper-Threading to double its thread count. Clock speeds favor AMD heavily, with the Ryzen boosting to 4.10 GHz from a 2000 MHz base, while the Xeon operates at a modest 1300 MHz base and 2.10 GHz boost. Cache hierarchies also diverge: both share 64 KB L1 per core, but the Ryzen has 512 KB L2 per core versus the Xeon's 256 KB, and the Ryzen's L3 cache is 8 MB shared, while the Xeon allocates 1.5 MB per core.

The memory and platform support reveal their different target markets. The Ryzen 7 4700U uses dual-channel DDR4 with 51.2 GB/s bandwidth and no ECC support, while the Xeon D-1577 supports both DDR3 and DDR4 in dual-channel configuration, with ECC memory enabled. The Intel chip also offers 24 PCIe Gen 3 lanes, while the AMD part uses Gen 3 without a specified lane count. The Xeon includes no integrated graphics, whereas the Ryzen features Radeon Graphics with 448 SPs, making it a complete APU solution.

Where Each One Wins

The AMD Ryzen 7 4700U is clearly optimized for scenarios where single-threaded performance and power efficiency are paramount. Its 15-watt TDP, compared to the Xeon's 45-watt rating, makes it suitable for thin-and-light mobile devices where thermal constraints are tight. The 35.3% advantage in Cinebench R15 single-core and the 15.7% win in R15 multi-core demonstrate that for legacy applications and lightly-threaded workloads, the Ryzen provides superior responsiveness. The integrated Radeon Graphics 448SP also gives it a decisive edge for systems that need graphical output without a discrete GPU.

Conversely, the Intel Xeon D-1577 wins in heavily threaded, sustained workloads that can leverage its 32 threads. The 21.4% margin in Cinebench R23 multi-core is the clearest indicator of this strength, showing that modern render engines and server-type applications scale well with the Xeon's core count. Its ECC memory support and server/workstation market segment make it appropriate for always-on systems where data integrity and reliability are critical. The 45-watt TDP, while higher, is still modest for a 16-core server processor, allowing dense deployments in networking and storage appliances.

The benchmark data also shows a temporal split. The Ryzen 7 4700U performs better in the older R15 test, while the Xeon D-1577 excels in the newer R23. This suggests that as software evolves to utilize more threads, the Xeon's advantage will grow, whereas legacy software will continue to favor the AMD part's higher clock speeds.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Ryzen 7 4700U features 8 cores and 8 threads, while the Intel Xeon D-1577 doubles both to 16 cores and 32 threads. Base clocks are 2000 MHz for AMD versus 1300 MHz for Intel, and boost clocks are 4.10 GHz versus 2.10 GHz respectively. TDP ratings are 15 watts for the Ryzen and 45 watts for the Xeon.

Socket compatibility is entirely different, with the AMD part using AMD Socket FP6 and the Intel part using Intel BGA 1667. Process technology is 7 nm from TSMC for AMD versus 14 nm from Intel for the Xeon. Transistor counts are 9,800 million versus 3,200 million, and die sizes are 156 mm² versus 246 mm². L2 cache is 512 KB per core on the Ryzen versus 256 KB per core on the Xeon, while L3 cache configuration is 8 MB shared versus 1.5 MB per core.

Memory support sees the AMD chip limited to DDR4, while the Intel chip supports both DDR3 and DDR4. Memory bandwidth is specified at 51.2 GB/s for the Ryzen, with no figure given for the Xeon. ECC memory support is absent on the AMD part but present on the Intel. Integrated graphics are included on the Ryzen 7 4700U as Radeon Graphics 448SP, while the Xeon has none. The market segments differ, with AMD targeting Mobile and Intel targeting Server/Workstation. Release dates are also far apart, with the Ryzen launching in January 2020 and the Xeon in February 2016.
