AMD Ryzen 5 2400GE vs Intel Core i5-5675C Comparison

The AMD Ryzen 5 2400GE and the Intel Core i5-5675C are both 14 nm desktop processors with four physical cores, but they represent two very different design philosophies from different eras. The benchmark data shows a decisive performance gap, with the Ryzen 5 2400GE winning every single head-to-head comparison. However, the Intel part retains a distinct advantage in platform features, particularly in PCIe lane allocation and integrated graphics capabilities, making the choice between them less straightforward than raw compute scores might suggest.

Head-to-Head Benchmarks

The benchmark results are remarkably consistent across every test, with the AMD Ryzen 5 2400GE winning all six direct comparisons. In Cinebench R15 multi-core, the Ryzen 5 2400GE scores 615 against the Intel Core i5-5675C's 495, a 24.2% advantage. The single-core test in the same suite shows a nearly identical margin, with 86 points versus 69 points, translating to a 24.6% lead for AMD. This consistency suggests a fundamental architectural advantage rather than a workload-specific quirk.

Moving to Cinebench R20, the pattern holds. The Ryzen 5 2400GE posts 2564 in multi-core versus 2063 for the Intel chip, a 24.3% delta. Single-core results in R20 show 362 against 291, a 24.4% margin. The latest Cinebench R23 version reinforces the trend: the AMD part scores 6107 multi-core and 862 single-core, while Intel manages 4912 and 693 respectively. Both deltas sit at 24.3% and 24.4%, showing that the performance gap has not narrowed with newer benchmark versions.

It is importantly the Intel Core i5-5675C has additional benchmark data available—Geekbench multi-core and single-core scores of 4159 and 1388—but no corresponding Geekbench results exist for the AMD part in this data set. Even without that comparison, the Cinebench family of tests provides a comprehensive picture. The Ryzen 5 2400GE's average benchmark score of 1766 slightly exceeds the Intel chip's 1759, and both sit in the 41st percentile among all CPUs. The nearest-rival data confirms they are closely matched in overall standing, with the Ryzen 5 2400GE showing a 0.4% delta over the Intel chip, while the reverse comparison shows the Intel part at -0.4% relative to AMD.

Where Each One Wins

The AMD Ryzen 5 2400GE wins decisively in all compute-focused workloads represented by the Cinebench suite. Multi-threaded rendering tasks, which leverage all available execution resources, show the AMD part consistently ahead by roughly 24% across R15, R20, and R23 versions. This makes it the clear choice for content creation, 3D rendering, or any application that can utilize its eight threads. The single-core results are equally one-sided, with the AMD part leading by a similar 24% margin, indicating that its Zen architecture provides better instruction-per-clock efficiency in this comparison.

The Intel Core i5-5675C, despite losing every benchmark, retains advantages in areas not captured by the Cinebench scores. Its 16 PCIe lanes (Gen 3) versus the AMD part's 8 lanes give it superior expansion potential for discrete graphics and NVMe storage configurations. The Intel chip also features Iris Pro Graphics 6200, which historically offers stronger integrated graphics performance than the Radeon RX Vega 11 in certain legacy scenarios, though the data does not provide direct graphics benchmarks. For users prioritizing CPU-only compute, the AMD part is the unambiguous winner; for those building a system with heavy I/O requirements, the Intel chip's platform advantages may compensate for its lower processing throughput.

Architecture Differences

The two processors come from different architectural generations and design teams. The AMD Ryzen 5 2400GE uses the Zen architecture with the Raven Ridge codename, part of the 2000 series. It is built by GlobalFoundries on a 14 nm process and packs 4,950 million transistors into a 210 mm² die. The Intel Core i5-5675C uses the Broadwell architecture, also on a 14 nm process but fabricated by Intel, with a smaller 182 mm² die size and no transistor count listed in the data.

Cache hierarchies differ significantly. The AMD part allocates 128 KB of L1 cache per core and 512 KB of L2 per core, while the Intel chip has 64 KB L1 and 256 KB L2 per core. Both share 4 MB of L3 cache. This means the AMD processor has twice the per-core L1 and L2 capacity, which likely contributes to its single-threaded advantage. The AMD part also features 8 threads versus Intel's 4, doubling the logical processor count for multi-threaded workloads.

Memory support represents a major architectural split. The Ryzen 5 2400GE uses DDR4 with dual-channel access and a theoretical bandwidth of 46.9 GB/s. The Intel Core i5-5675C uses DDR3, also dual-channel, with a significantly lower 25.6 GB/s bandwidth. This 21.3 GB/s difference in memory bandwidth may explain part of the performance gap in memory-sensitive workloads. Both processors have unlocked multipliers, and neither supports ECC memory. The AMD part uses the AM4 socket, while Intel uses Socket 1150, making them incompatible with each other's motherboards.

Specification Differences

The most obvious divergence is in thread count: the AMD Ryzen 5 2400GE offers 8 threads through simultaneous multithreading, while the Intel Core i5-5675C is limited to 4 threads. Base clocks are close, with AMD at 3.20 GHz and Intel at 3.10 GHz, but boost clocks show AMD ahead at 3.80 GHz versus 3.60 GHz. Thermal design power differs substantially, with the AMD part rated at 35W versus Intel's 65W, making the Ryzen far more power-efficient despite its higher performance.

Memory bandwidth is another clear differentiator, as noted above, with AMD's 46.9 GB/s nearly doubling Intel's 25.6 GB/s. The PCIe lane count also differs: AMD provides 8 Gen 3 lanes from the CPU, while Intel provides 16. The integrated graphics solutions are different, with AMD featuring Radeon RX Vega 11 and Intel featuring Iris Pro Graphics 6200, though no direct graphics benchmarks exist in this data. The AMD processor was released on April 18, 2018, while Intel's chip launched on May 14, 2015, a gap of nearly three years.

The Intel Core i5-5675C has a listed launch MSRP of $276, while the AMD part has no MSRP data available. The AMD processor's part number is YD2400C6M4MFBYD2400C6FBMPK, and Intel's is SR2B6SR2FX. Both are desktop parts with active production status and unlocked multipliers. The AMD chip's cache configuration shows 128 KB L1 per core and 512 KB L2 per core, versus Intel's 64 KB and 256 KB respectively, with both sharing 4 MB L3.
