AMD Ryzen 7 3700U vs Intel Xeon W3570 Comparison

The Verdict

The data separates these two processors clearly. The AMD Ryzen 7 3700U is the decisive winner in the only benchmark where both were measured, the Cinebench R15 multicore test, where it scores 672 against the Intel Xeon W3570's 279. That is a 140.9% advantage for the AMD part. The Ryzen 7 3700U also holds a higher average benchmark score of 968 compared to 955 for the Xeon W3570, and a slightly higher percentile ranking at 26 versus 25.

The Xeon W3570, despite its higher base clock of 3.20 GHz versus 2.30 GHz, is an end-of-life design from 2009. Its performance class today is defined by its nearest rivals: the Intel Celeron N5105, the Intel Xeon W3550, the AMD Athlon X4 870K, and the Intel Core i7-950. The Ryzen 7 3700U, by contrast, sits alongside the Intel Core i5-2400S, the Intel Xeon X5570, and the Intel Celeron N5100. For anyone choosing between these two, the Ryzen 7 3700U is the pick for raw compute, for modern platform features, and for any mobile or power-sensitive use case. The Xeon W3570 only makes sense if a triple-channel DDR3 memory bus or ECC memory support is a hard requirement, as those features are absent on the AMD part.

Architecture Differences

The architectural gap between these two processors spans nearly a decade of development. The AMD Ryzen 7 3700U is built on the Zen+ architecture, with the codename Picasso, and belongs to the 3000 series. It uses a 12 nm process node from GlobalFoundries, packing 4,940 million transistors onto a 210 mm² die. The Intel Xeon W3570 is a Nehalem architecture part, codenamed Bloomfield, fabricated on Intel's 45 nm process with just 731 million transistors on a larger 263 mm² die.

The cache structures differ significantly. The Ryzen 7 3700U has 96 KB of L1 cache per core and 512 KB of L2 cache per core, with 4 MB of shared L3 cache. The Xeon W3570 has 64 KB of L1 per core and 256 KB of L2 per core, but doubles the shared L3 to 8 MB. The AMD part compensates with a smaller process node and newer architecture, while the Intel part relies on a larger pool of last-level cache.

Memory support is a major divergence. The Ryzen 7 3700U uses DDR4 memory in a dual-channel configuration, while the Xeon W3570 uses DDR3 in a triple-channel configuration. The Xeon also supports ECC memory, a feature the Ryzen 7 3700U lacks. The integrated graphics are exclusive to the AMD part, which ships with a Radeon Vega 10 iGPU. The Xeon W3570 has no integrated graphics at all, requiring a discrete GPU for any display output.

The platforms are entirely incompatible. The Ryzen 7 3700U uses AMD Socket FP5, while the Xeon W3570 uses Intel Socket 1366. PCIe generations also differ, with the Ryzen part supporting Gen 3 and the Xeon part limited to Gen 2. The production status tells the story: the Ryzen 7 3700U is listed as active, while the Xeon W3570 is end-of-life.

Head-to-Head Benchmarks

Only one benchmark appears in both processors' result sets, the Cinebench R15 multicore test. The AMD Ryzen 7 3700U scores 672, while the Intel Xeon W3570 scores 279. The delta is 140.9%, meaning the Ryzen part is more than two and a half times faster in this workload. This is a striking result given that both CPUs have 4 cores and 8 threads. The Ryzen 7 3700U's newer Zen+ architecture and 12 nm process clearly deliver far higher instructions per clock and better multithreaded scaling than the 45 nm Nehalem design.

The Xeon W3570 does have additional benchmark results not shared with the Ryzen 7 3700U. It scores 1165 in Cinebench R20 multicore, 164 in Cinebench R20 single-core, 2776 in Cinebench R23 multicore, and 392 in Cinebench R23 single-core. These numbers cannot be compared directly to the Ryzen 7 3700U because the AMD part has no corresponding results in the database. The average benchmark score, however, aggregates all recorded tests: the Ryzen 7 3700U averages 968, and the Xeon W3570 averages 955, a 13-point gap in favor of AMD.

The percentile rankings reinforce the same conclusion. The Ryzen 7 3700U sits at the 26th percentile of all CPUs, while the Xeon W3570 sits at the 25th. The Ryzen part's nearest rival, the Intel Core i5-2400S, matches its average score exactly at 968 with a 0% delta. The Xeon W3570's closest competitor, the Intel Celeron N5105, also matches at 955 with a 0% delta. The overall picture is that the Ryzen 7 3700U performs at a slightly higher tier than the Xeon W3570, despite the Intel part's higher clock speeds.

Specification Differences

The two processors differ across nearly every specification field. The Ryzen 7 3700U has a base clock of 2.30 GHz and a boost clock of 4.00 GHz, while the Xeon W3570 has a higher base clock of 3.20 GHz but a much lower boost clock of 3.47 GHz. The AMD part boosts much more aggressively, gaining 1.70 GHz over its base, while the Intel part gains only 0.27 GHz.

The TDP is a dramatic differentiator. The Ryzen 7 3700U is rated at 15 watts, while the Xeon W3570 is rated at 130 watts. That is an 8.7x difference in power draw, making the Ryzen part suitable for mobile devices and fanless designs, while the Xeon part demands serious cooling and a workstation-class power delivery system.

The manufacturing technology is equally divergent. The Ryzen 7 3700U uses a 12 nm node from GlobalFoundries, while the Xeon W3570 uses a 45 nm node from Intel. Transistor counts reflect the process gap: 4,940 million for AMD versus 731 million for Intel. Die sizes are 210 mm² for AMD and 263 mm² for Intel. The AMD part crams more than six times the transistors into a smaller die.

Cache and memory differences have been noted above, but the full list of differing fields includes: L1 cache (96 KB per core vs 64 KB), L2 cache (512 KB per core vs 256 KB), L3 cache (4 MB shared vs 8 MB shared), memory type (DDR4 vs DDR3), memory channel count (dual vs triple), ECC support (false vs true), PCIe generation (Gen 3 vs Gen 2), integrated graphics (Radeon Vega 10 vs none), market segment (Mobile vs Server/Workstation), production status (Active vs End-of-life), release date (2019-01-05 vs 2009-03-29), and part number (YM370BC4T4MFG vs SLBES). Both are locked from multiplier overclocking and have no launch MSRP recorded.

Where Each One Wins

The AMD Ryzen 7 3700U wins the only direct benchmark comparison, and it wins on the attributes that matter most for modern users. The 15-watt TDP makes it viable for laptops and compact systems, and the 4.00 GHz boost clock gives it strong single-threaded headroom. The Radeon Vega 10 iGPU eliminates the need for a discrete graphics card in basic systems. The active production status and 2019 release date mean it is a current product with modern platform support, including DDR4 memory and PCIe Gen 3. The 140.9% lead in Cinebench R15 multicore over the Xeon W3570, combined with the higher average score of 968 versus 955, makes it the clear choice for any general-purpose compute workload.

The Intel Xeon W3570 has a narrow set of advantages, but they are real. It supports ECC memory, which is critical for error-sensitive server or workstation environments where data corruption is unacceptable. Its triple-channel DDR3 memory bus provides more memory channels than the Ryzen 7 3700U's dual-channel configuration, which can benefit memory-bandwidth-intensive tasks. The larger 8 MB shared L3 cache, double the AMD part's 4 MB, may also help in workloads with high cache reuse. The higher base clock of 3.20 GHz gives it a slight advantage in sustained all-core loads that do not boost, though its 3.47 GHz boost clock is far below the Ryzen's 4.00 GHz. For a legacy workstation requiring ECC and triple-channel memory, the Xeon W3570 remains a functional option. For everything else, the Ryzen 7 3700U is the superior processor.
