AMD Ryzen 3 4300GE vs Intel Xeon E5-2628L v3 Comparison

The AMD Ryzen 3 4300GE and the Intel Xeon E5-2628L v3 represent two fundamentally different answers to the question of what a low-power CPU should be. The Ryzen 3 is a modern 7nm desktop part with a focus on efficiency and integrated graphics, while the Xeon is a 22nm server/workstation processor built for multi-threaded throughput in a server chassis. Benchmark results place them neck-and-neck overall, with the Ryzen 3 4300GE holding a perfect 6-0 win record in head-to-head Cinebench tests, yet the underlying architectures and target markets tell a more complex story than the raw scores suggest.

Where Each One Wins

The data paints a clear picture of a split by workload category, despite the near-identical average benchmark scores. The AMD Ryzen 3 4300GE wins every single Cinebench test in the head-to-head comparison, but the margins are remarkably thin. In multi-core tests, the Ryzen 3 4300GE scores 961, 4006, and 9540 in R15, R20, and R23 respectively, versus 949, 3955, and 9417 for the Xeon E5-2628L v3. This gives the AMD part a consistent 1.3% advantage in multi-threaded work. The single-core results follow the same pattern, with the Ryzen 3 4300GE leading by 1.5% in R15 (135 vs 133) and 1.3% in both R20 (565 vs 558) and R23 (1346 vs 1329).

However, the Xeon E5-2628L v3 is not without its own domain of superiority. With 10 cores and 20 threads versus the Ryzen 3 4300GE's 4 cores and 8 threads, the Xeon is designed for scenarios where raw core count matters more than per-core speed. The data shows that despite having 2.5 times more cores, the Xeon only trails by 1.3% in multi-core benchmarks, implying that the Ryzen 3 4300GE's per-core performance is dramatically higher. For workloads that are heavily parallelized but also sensitive to clock speeds, the Xeon's 20 threads provide a structural advantage that the Ryzen 3 4300GE simply cannot match in terms of raw thread scheduling flexibility. The Xeon is the choice for server environments where ECC memory and quad-channel bandwidth are non-negotiable, while the Ryzen 3 4300GE wins in any scenario that benefits from higher clock speeds or integrated graphics.

Architecture Differences

The architectural gap between these two processors is generational and profound. The AMD Ryzen 3 4300GE uses the Zen 2 architecture on TSMC's 7 nm process node, while the Intel Xeon E5-2628L v3 uses the Haswell architecture on Intel's 22 nm process. This node difference explains much of the performance-per-watt disparity: the Ryzen 3 4300GE has a TDP of 35 watts, while the Xeon E5-2628L v3 draws 75 watts. The transistor counts tell a similar story, with the Ryzen 3 4300GE packing 9,800 million transistors on a 156 mm² die, compared to the Xeon's 2,600 million transistors on a much larger 356 mm² die.

The cache hierarchies are also structured differently. Both have 64 KB of L1 per core, but the Ryzen 3 4300GE has 512 KB of L2 per core, while the Xeon E5-2628L v3 has 256 KB of L2 per core. The L3 cache is a major differentiator: the Ryzen 3 4300GE has 4 MB shared, while the Xeon E5-2628L v3 has 25 MB shared. This massive L3 advantage for the Xeon suggests it can handle larger working sets without hitting main memory, which is critical for database and virtualization workloads. The Ryzen 3 4300GE compensates with a higher base clock of 3.50 GHz and boost clock of 4.00 GHz, versus the Xeon's 2.00 GHz base and 2.50 GHz boost. The Xeon also offers quad-channel memory support and 40 PCIe Gen 3 lanes (CPU only), while the Ryzen 3 4300GE is limited to dual-channel memory and Gen 3 PCIe without a lane count specified.

Head-to-Head Benchmarks

The benchmark data shows a consistent but narrow victory for the AMD Ryzen 3 4300GE across all six Cinebench tests. The largest margin comes in the Cinebench R15 single-core test, where the Ryzen 3 4300GE scores 135 versus 133 for the Xeon E5-2628L v3, a 1.5% advantage. This is notable because the Xeon's lower clock speeds and older architecture should theoretically handicap it more severely in single-threaded performance; the fact that it trails by only 1.5% suggests the Xeon's Haswell cores are more efficient per clock than expected, or that the Ryzen 3 4300GE's boost clock is not fully sustained in this workload.

In multi-core tests, the Ryzen 3 4300GE wins by 1.3% in all three Cinebench versions: 961 vs 949 in R15, 4006 vs 3955 in R20, and 9540 vs 9417 in R23. Given that the Xeon has 10 cores and 20 threads compared to the Ryzen 3 4300GE's 4 cores and 8 threads, this result is extraordinary. The Ryzen 3 4300GE achieves near-parity in multi-threaded performance with a processor that has 150% more cores and 150% more threads. This implies that the Ryzen 3 4300GE's per-core performance is roughly 2.5 times higher than the Xeon's, which aligns with the clock speed difference (4.00 GHz vs 2.50 GHz boost) but also points to significant IPC improvements from Zen 2 over Haswell. The average benchmark scores confirm the overall parity: 2759 for the Ryzen 3 4300GE and 2724 for the Xeon E5-2628L v3, with both sitting at the 50th percentile of all CPUs.

Specification Differences

The specification sheet reveals stark contrasts between these two processors. The AMD Ryzen 3 4300GE has 4 cores and 8 threads, while the Intel Xeon E5-2628L v3 has 10 cores and 20 threads. Clock speeds differ dramatically: the Ryzen 3 4300GE runs at 3.50 GHz base and 4.00 GHz boost, while the Xeon runs at 2000.00 MHz base (which converts to 2.00 GHz) and 2.50 GHz boost. TDP is a major differentiator: 35 watts for the AMD part versus 75 watts for the Intel part. The Ryzen 3 4300GE uses the AMD Socket AM4, while the Xeon E5-2628L v3 uses the Intel Socket 2011-3. Process nodes are 7 nm (TSMC) for AMD and 22 nm (Intel) for the Xeon, with transistor counts of 9,800 million versus 2,600 million and die sizes of 156 mm² versus 356 mm².

Cache configurations differ significantly: the Ryzen 3 4300GE has 512 KB L2 per core and 4 MB shared L3, while the Xeon E5-2628L v3 has 256 KB L2 per core and 25 MB shared L3. Memory support is dual-channel for the AMD part with 51.2 GB/s bandwidth, versus quad-channel for the Intel part with 59.7 GB/s bandwidth. Both support DDR4 and ECC memory. The Ryzen 3 4300GE includes Radeon Vega 6 integrated graphics, while the Xeon has no integrated graphics. The Ryzen 3 4300GE has an unlocked multiplier, while the Xeon E5-2628L v3 does not. The Xeon offers 40 PCIe Gen 3 lanes (CPU only), while the Ryzen 3 4300GE's PCIe lane count is not specified. Production statuses differ: the Ryzen 3 4300GE is Active, while the Xeon E5-2628L v3 is End-of-life. The Xeon launched in 2014 with a launch MSRP of $1364, while the Ryzen 3 4300GE launched in 2020 with no listed MSRP. The Ryzen 3 4300GE targets the Desktop market, while the Xeon targets Server/Workstation.

The Verdict

The data suggests that the AMD Ryzen 3 4300GE is the superior choice for desktop users who prioritize power efficiency, integrated graphics, and higher clock speeds. Its 35-watt TDP, 7nm process, and 4.00 GHz boost clock make it ideal for compact builds or always-on systems where heat and noise are concerns. The fact that it matches or beats a 10-core server processor in all Cinebench tests, despite having only 4 cores, indicates that its per-core performance is exceptional. Users who need a capable all-in-one solution with Radeon Vega 6 graphics and do not require massive thread counts should pick the Ryzen 3 4300GE.

The Intel Xeon E5-2628L v3, despite its age and end-of-life status, remains relevant for server and workstation deployments where the 20 threads and 25 MB of L3 cache are critical. Its quad-channel memory support and 40 PCIe Gen 3 lanes provide bandwidth advantages that the Ryzen 3 4300GE cannot match. The Xeon's 75-watt TDP is higher, but in a server environment, that power budget is justified by the additional cores and memory throughput. Organizations running heavily threaded workloads such as virtualization, database servers, or render farms that can utilize 20 threads will find the Xeon E5-2628L v3 more suitable, particularly given its ECC memory support and server-grade feature set. For desktop users, the Ryzen 3 4300GE is the clear winner; for server workloads, the Xeon's core count and memory architecture make it the logical choice, even if benchmark scores are nearly identical.
