CPU Comparison
Intel Xeon 6349P vs Intel Xeon 6377P
A side-by-side comparison of specs, performance and value. The Intel Xeon 6349P is a 6-core, 12-thread entry-level server processor based on the Raptor Lake-R platform, offering up to 5.7 GHz turbo, DDR5-4800 memory, and PCIe 5.0 for small business servers and workstations.
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong per-core performance and good memory bandwidth make it effective for office productivity, light databases, and business applications, though heavy multi-threaded workloads may prefer more cores.
Strong lightly threaded performance in office and business applications; more cores from EPYC 4004/4005 can win in heavily threaded workloads.
Gaming
Not targeted at gaming, but its high clocks give competitive single-thread performance; however, lack of E-cores and limited core count reduce heavy multitasking advantage compared to gaming-optimized desktop CPUs.
Capable of high-refresh-rate gaming in a desktop board, but not its intended market; modern desktop CPUs often deliver better gaming performance for the money.
Virtualization
Support for ECC memory, VT-x/VT-d, and high clocks provides a stable, responsive platform for small virtualization hosts running a modest number of VMs.
Adequate for small virtualization hosts, but limited core count and memory channels constrain consolidation ratios compared to many-core competitors.
Efficiency
95 W TDP is reasonable for a 6-core server CPU at these frequencies, but higher-core competitors at similar TDP may deliver better performance-per-watt in heavily threaded scenarios.
95W TDP is low for a 12-core server CPU, but performance-per-watt is less compelling versus newer AMD architectures with more cores at similar power.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware
- Suitable only for CPU-based inference or small models
- For serious AI workloads, GPUs or specialized accelerators are required
- No dedicated AI acceleration like AMX or NPU.
- AVX2 but no AVX-512, limiting wide-vector inference throughput.
- Suitable only for CPU-based AI inference at modest scale.
Content Creation
Gaming
- High single-core turbo up to 5.7 GHz benefits many game engines
- No hybrid E-core design, so consistent behavior under mixed CPU/GPU loads
- For pure gaming, mainstream desktop CPUs often offer better value and higher core counts
- High clock speeds give solid single-threaded performance.
- Not optimized for gaming; lacks integrated graphics.
- Desktop CPUs at lower price points often match or beat it in games.
