AMD Ryzen 3 PRO 7330U vs Intel Xeon E5-2676 v3 Comparison

Where Each One Wins

The benchmark data presents a clear and consistent picture: the Intel Xeon E5-2676 v3 wins every single head-to-head test recorded in the database. Across all six Cinebench comparisons, the Intel part takes the top score, leaving the AMD Ryzen 3 PRO 7330U without a single victory. The margin is narrow but uniform, with the Xeon leading by approximately 3% in every workload.

Breaking down the wins by category, the Xeon E5-2676 v3 dominates both multi-core and single-core tests. In Cinebench R15 multicore, it scores 1102 against the Ryzen's 1068, a 3.1% advantage. The single-core R15 run shows the same pattern: 155 versus 150, a 3.2% lead. Moving to Cinebench R20, the Xeon posts 4592 multicore and 648 single-core, while the Ryzen manages 4454 and 628, respectively, with the delta sitting at 3% for both. The R23 results mirror this exactly: 10935 against 10605 in multicore and 1543 against 1497 in single-core, again a 3% gap.

The data shows no workload category where the AMD Ryzen 3 PRO 7330U pulls ahead. Whether the test stresses all threads or just one, the Intel Xeon E5-2676 v3 maintains its edge. This uniformity is notable: the performance difference is not a product of cache-sensitive workloads or memory bandwidth quirks, it is a consistent baseline advantage across the Cinebench suite.

In terms of broader positioning, the Ryzen 3 PRO 7330U sits at the 52nd percentile among all CPUs, while the Xeon E5-2676 v3 sits at the 53rd percentile. Their average benchmark scores are also close: 3063 for the AMD and 3163 for the Intel, a difference of roughly 3.3%. This aligns with the head-to-head deltas and confirms that the Xeon's victory is real but modest.

Architecture Differences

The two processors come from fundamentally different design eras and serve different market segments. The AMD Ryzen 3 PRO 7330U is built on the Zen 3 architecture, specifically the Barcelo-R codename, using a 7 nm process from TSMC. It belongs to the 7000 series and targets the mobile segment, with a 15 watt TDP. Its silicon packs 10,700 million transistors on a 180 mm² die.

The Intel Xeon E5-2676 v3 is a Haswell-EP part, using the older Haswell architecture on a 22 nm Intel process. It is a server and workstation chip with a 120 watt TDP, and its die size is larger at 356 mm², yet it contains far fewer transistors: only 2,600 million. This reflects the density advantage of the 7 nm node over the older 22 nm process.

Core and thread counts differ substantially. The Ryzen offers 4 cores and 8 threads, while the Xeon provides 12 cores and 24 threads. Despite having three times the core count, the Xeon only manages a 3% performance lead in threaded workloads, a signal of the Zen 3 architecture's efficiency and higher clock speeds.

Clock speeds also diverge. The AMD chip has a base clock of 2.30 GHz and a boost clock of 4.30 GHz, while the Intel part runs at 2.40 GHz base and 3.00 GHz boost. The Ryzen's much higher boost clock partially compensates for its fewer cores, but not enough to overcome the Xeon's thread advantage.

Cache hierarchies differ as well. Both share 64 KB of L1 cache per core. The Ryzen has 512 KB of L2 per core, while the Xeon has 256 KB per core. For L3, the AMD chip uses 8 MB shared, whereas the Intel part has 30 MB shared. The larger shared L3 on the Xeon likely helps in server workloads with many concurrent threads.

Memory support also separates the two. The Ryzen supports DDR4 in a dual-channel configuration with 51.2 GB/s of bandwidth. The Xeon supports both DDR3 and DDR4 across a quad-channel bus, achieving 68.3 GB/s. Both support ECC memory, which matters for reliability in professional environments. PCIe connectivity differs too: the AMD provides Gen 3 with 16 lanes from the CPU, while the Intel offers Gen 3 with 40 lanes, a significant advantage for expansion-heavy server platforms.

The Ryzen includes integrated Radeon Graphics with Vega 6, while the Xeon has no integrated graphics at all. The production status also differs: the Ryzen is active, while the Xeon is end-of-life. The Ryzen was released on 2023-01-03, whereas no release date is recorded for the Xeon.

The Verdict

For users prioritizing raw multi-threaded throughput in Cinebench, the Intel Xeon E5-2676 v3 is the better choice. It wins every recorded benchmark, and its 12 cores and 24 threads give it a structural advantage in heavily parallel workloads. The data shows a consistent 3% lead across all tests, and its 53rd percentile ranking places it slightly above the Ryzen's 52nd percentile.

However, the narrowness of that lead is striking. A processor with three times the cores and a quad-channel memory bus only outperforms a 15 watt mobile chip by 3%. This suggests that the Ryzen 3 PRO 7330U's Zen 3 architecture, with its 7 nm process and 4.30 GHz boost clock, is vastly more efficient per watt and per core. For mobile applications, where power consumption and heat are constraints, the Ryzen is clearly the more practical part.

The Xeon E5-2676 v3 targets server and workstation sockets, with 40 PCIe lanes and support for both DDR3 and DDR4. Its end-of-life status and 120 watt TDP make it less attractive for new builds, but its benchmark scores remain competitive. The Ryzen, by contrast, is an active product with integrated graphics, making it a viable option for compact systems that do not require a discrete GPU.

The choice depends on the platform. If the workload is heavily threaded and runs on a server motherboard with ample cooling, the Xeon's edge is real. If the system needs to be small, efficient, and still deliver decent performance, the Ryzen's 15 watt envelope and active production status are compelling. The database does not show a scenario where the Ryzen wins a benchmark, but the overall score gap is small enough that the architectural efficiency of the Zen 3 part cannot be ignored.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. In Cinebench R15 multicore, the Xeon scores 1102 against the Ryzen's 1068, a 3.1% advantage. The R15 single-core test shows 155 versus 150, a 3.2% lead. The R20 multicore run has the Xeon at 4592 and the Ryzen at 4454, a 3% gap. The R20 single-core shows 648 against 628, again 3.1%. The R23 multicore results are 10935 versus 10605, a 3% difference, and the R23 single-core shows 1543 versus 1497, also 3%.

These numbers tell a simple story. The Intel Xeon E5-2676 v3 is consistently about 3% faster across every Cinebench version and every workload type. The largest margin is in R15 single-core at 3.2%, while the smallest is in R20 multicore, R23 multicore, and R23 single-core, all at 3%.

The average benchmark scores reinforce this. The Xeon averages 3163 across all recorded benchmarks, while the Ryzen averages 3063, a difference of exactly 100 points, or about 3.3%. The nearest rivals for each chip also cluster around these values: the Ryzen's closest competitor, the Intel Xeon E5-2618L v3, scores 3066, just 0.1% away, and the Xeon's closest rival, the AMD Ryzen 5 5560U, scores 3162, essentially tied.

The data does not show any workload where the Ryzen closes the gap or overtakes the Xeon. Even in single-core tests, where the Ryzen's 4.30 GHz boost clock might be expected to help, the Xeon's Haswell architecture holds a slight edge. This suggests that the Xeon's advantage is a fundamental property of its design, not a quirk of a particular benchmark version.

Specification Differences

The two processors differ in nearly every specification category. The AMD Ryzen 3 PRO 7330U uses a 7 nm process from TSMC, while the Intel Xeon E5-2676 v3 uses a 22 nm process from Intel. The transistor counts are 10,700 million versus 2,600 million, and the die sizes are 180 mm² versus 356 mm².
