AMD Ryzen 3 PRO 4350G vs Intel Xeon E-2126G Comparison

The AMD Ryzen 3 PRO 4350G wins six of the eight head-to-head benchmark tests in the database, but the Intel Xeon E-2126G takes the two Geekbench tests by a wide margin. The recorded data shows a clear split: the AMD part dominates every Cinebench test, while the Intel part dominates every Geekbench test. Both CPUs sit at the 51st percentile among all CPUs in the database, yet their performance profiles could hardly be more different.

Head-to-Head Benchmarks

The AMD Ryzen 3 PRO 4350G is the majority winner, taking 6 of 8 tests. Its cleanest sweep is in the Cinebench suite. In Cinebench R23 multicore, the AMD scores 9287 against the Intel's 8891, a 4.3% lead. In R23 single-core, the AMD scores 1311 against 1255, also a 4.3% lead. The R20 results follow the same pattern: 3900 versus 3734 in multicore (4.3%) and 550 versus 527 in single-core (4.2%). The R15 results are consistent: 936 versus 896 in multicore (4.3%) and 132 versus 126 in single-core (4.5%).

The Intel Xeon E-2126G answers with the two largest margins in the entire comparison. In Geekbench multicore, the Intel scores 5743 against the AMD's 4608, a 24.6% lead. In Geekbench single-core, the Intel scores 1565 against 1470, a 6.5% lead. The 24.6% Geekbench multicore margin is more than five times larger than any Cinebench margin in either direction.

The average benchmark scores reflect this split. The Intel averages 2842 across all recorded tests, while the AMD averages 2774. The Intel's average is pulled up by its Geekbench multicore result, while the AMD's average is more consistent across the Cinebench suite. Looking at nearest rivals, the Intel's 2842 average places it within 0.6% of the Intel Core i7-11370H (2861) and 0.1% of the Intel Core i7-6800K (2838). The AMD's 2774 average is essentially tied with the Intel Core i7-5930K (2775, 0% delta) and within 0.1% of the Intel Xeon D-1567 (2770).

The Verdict

The data points to the AMD Ryzen 3 PRO 4350G as the better choice for Cinebench-style rendering workloads. It wins all six Cinebench tests with margins between 4.2% and 4.5%, and it does so with a lower TDP of 65W versus 80W. The AMD part is also still in active production, while the Intel part is end-of-life.

The Intel Xeon E-2126G is the better choice for Geekbench-style workloads. Its 24.6% multicore lead and 6.5% single-core lead are decisive, and its higher average benchmark score of 2842 versus 2774 reflects that strength. The Intel also has a higher boost clock at 4.50 GHz versus 4.00 GHz and more L3 cache at 12 MB versus 4 MB.

The choice depends on the workload. For rendering and multi-threaded Cinebench-style tasks, the AMD wins. For Geekbench-style general-purpose tasks, the Intel wins. The AMD's active production status and lower TDP make it the safer long-term pick for a desktop build, while the Intel's server/workstation segment and ECC support make it a candidate for workstation use.

Architecture Differences

The two CPUs represent different architectural generations and process nodes. The Intel Xeon E-2126G uses Coffee Lake architecture on a 14 nm process fabricated by Intel. The AMD Ryzen 3 PRO 4350G uses Zen 2 architecture on a 7 nm process fabricated by TSMC. The process node difference is substantial: 7 nm versus 14 nm.

Core and thread counts differ in an interesting way. The Intel has 6 cores and 6 threads, meaning no simultaneous multithreading. The AMD has 4 cores and 8 threads, using simultaneous multithreading to double its thread count. Despite having fewer physical cores, the AMD matches or exceeds the Intel in every Cinebench test.

Cache architecture differs significantly. The Intel has 12 MB of shared L3 cache, while the AMD has 4 MB of shared L3. The AMD compensates with 512 KB of L2 per core, double the Intel's 256 KB per core. Both have 64 KB of L1 per core.

The AMD die contains 9,800 million transistors on a 156 mm² die, while the Intel die is 154 mm² with no recorded transistor count. The AMD's smaller process node allows it to pack more transistors into a similar die area.

Both CPUs support DDR4 memory with dual-channel buses, but the AMD has a higher memory bandwidth at 51.2 GB/s versus 42.7 GB/s for the Intel. Both support ECC memory. Both use PCIe Gen 3 with 16 lanes from the CPU.

Integrated graphics differ: the Intel has HD Graphics P630, while the AMD has Radeon Vega 6. The Intel is classified as a Server/Workstation part, while the AMD is a Desktop part. The Intel was released on 2018-07-11 and is end-of-life; the AMD was released on 2020-07-20 and is active.
