AMD Ryzen 5 7400 vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The benchmark data presents an unusually one-sided comparison. Across the eleven shared PassMark tests recorded in the database, the Intel Arc G3 EXTREME wins every single one. There are no tests where the AMD Ryzen 5 7400 takes the lead. The Intel part's dominance spans every category measured, from single-threaded performance to multi-threaded throughput, and from integer math to data compression.

The Intel Arc G3 EXTREME's largest margins come in compute-heavy workloads. In floating-point math, it scores 86,929 versus the AMD's 40,784, a 53.1% advantage. The physics test shows a similar pattern, with the Intel part at 2,515 against 1,150 for the AMD, a 54.3% lead. Prime number finding, which is highly sensitive to integer execution efficiency, shows the Intel part at 248 versus 79, a 68.1% gap, the largest single delta in the entire comparison.

For multi-threaded workloads, the Intel Arc G3 EXTREME delivers 30,659 in the PassMark multi-thread test, compared to 21,712 for the AMD Ryzen 5 7400, a 29.2% advantage. This suggests the Intel part handles heavily threaded applications more effectively, despite the AMD chip having 12 threads to the Intel's 14. Data compression and encryption also favor Intel, with the Arc G3 EXTREME scoring 307,094 versus 261,749 in compression (14.8% ahead) and 23,881 versus 14,865 in encryption (37.8% ahead).

The AMD Ryzen 5 7400's strongest relative showing is in integer math, where it trails by only 9%. That is the narrowest margin in the entire head-to-head set. The AMD part also remains competitive in random string sorting, trailing by 16.7%, and extended instructions, trailing by 17%. Even in these closer contests, though, the Intel part still comes out ahead.

The aggregate picture is clear. The Intel Arc G3 EXTREME holds an average benchmark score of 36,699 across its recorded suite, while the AMD Ryzen 5 7400 averages 42,055 across its own benchmark set. Interestingly, the AMD chip's average is higher, but that reflects the different benchmark suites recorded for each part, not the direct head-to-head results. In the eleven directly comparable tests, Intel wins all eleven.

Architecture Differences

The two processors come from fundamentally different design directions. The AMD Ryzen 5 7400 is a desktop part built on the Zen 4 architecture, codenamed Raphael, and belongs to the 7000 series. It uses a 5 nm process from TSMC with a stated transistor count of 6,570 million on a 71 mm² die. The Intel Arc G3 EXTREME is a mobile processor codenamed Panther Lake, built on Intel's own 3 nm node. No transistor count or die size is recorded for the Intel part in the database.

Core configuration differs sharply. The AMD Ryzen 5 7400 has 6 cores and 12 threads, relying on simultaneous multithreading to double its thread count. The Intel Arc G3 EXTREME has 14 cores and 14 threads, meaning each core corresponds to exactly one thread. The Intel part therefore has more physical cores but no SMT. This explains why the Intel chip's multi-thread lead (29.2%) is smaller than its lead in single-threaded work (24.3%): the AMD part's SMT helps it close the gap in threaded workloads, even with fewer physical cores.

Cache hierarchies are also distinct. The AMD Ryzen 5 7400 uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel Arc G3 EXTREME uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has larger per-core caches at every level and a larger L3 pool overall.

Memory support differs substantially. The AMD chip supports DDR5 over a dual-channel bus with a recorded memory bandwidth of 83.2 GB/s. The Intel part supports LPDDR5X, also dual-channel, but with a recorded bandwidth of 136.5 GB/s. That 64% bandwidth advantage helps explain the Intel part's strong showing in data compression and encryption tests, which often scale with memory throughput. The AMD processor supports ECC memory; the Intel part does not.

PCIe connectivity also diverges. The AMD Ryzen 5 7400 exposes Gen 5 with 24 lanes from the CPU. The Intel Arc G3 EXTREME exposes Gen 5 with only 4 lanes. The AMD part also has an unlocked multiplier, while the Intel part is locked. Both processors include integrated graphics: the AMD chip uses Radeon Graphics, and the Intel part uses Arc B390.

Head-to-Head Benchmarks

The largest win for the Intel Arc G3 EXTREME is in the prime number test, where it scores 248 against 79 for the AMD Ryzen 5 7400, a 68.1% advantage. This test is particularly sensitive to branch prediction and integer execution efficiency, and the Intel part's architecture handles it far better. The physics test shows a 54.3% lead for Intel (2,515 versus 1,150), and floating-point math shows a 53.1% lead (86,929 versus 40,784). These three tests are the clearest demonstrations of the Intel part's computational strengths.

Encryption is another major Intel win. The Arc G3 EXTREME scores 23,881 versus 14,865, a 37.8% margin. This test often exercises AES instructions and memory bandwidth, both of which favor the Intel part given its higher memory bandwidth and larger caches. The multi-thread test shows Intel ahead by 29.2% (30,659 versus 21,712), a solid margin but smaller than the compute-heavy tests, consistent with the AMD part's SMT partially compensating for its lower core count.

Single-threaded performance goes to Intel by 24.3%, with scores of 4,293 versus 3,248. The Intel part's higher boost clock of 4.70 GHz versus 4.30 GHz for the AMD chip likely contributes here, though the architecture and process node differences also play a role. Extended instructions show a 17% Intel lead (24,017 versus 19,924), and random string sorting shows a 16.7% Intel lead (37,331 versus 31,110).

Data compression, at 14.8% in favor of Intel (307,094 versus 261,749), is the closest of the memory-intensive tests. The smallest overall margin is integer math, where Intel leads by only 9% (71,164 versus 64,733). The AMD Ryzen 5 7400's strongest relative performance is in this test, suggesting its integer execution units are more competitive with the Intel part than its floating-point or memory subsystems are.
