Architecture Differences

The two processors come from different manufacturing approaches. The AMD Ryzen 7 5705G is built on TSMC's 7 nm process with 10,700 million transistors on a 180 mm² die. The Intel Core 5 221E uses Intel's 10 nm process with a 257 mm² die size; transistor count is not recorded in the database.

The core designs diverge significantly. The AMD part uses the Zen 3 architecture under the Cezanne codename, featuring 8 cores and 16 threads. The Intel part uses the Bartlett Lake codename, providing 14 cores and 20 threads. This core count difference drives most of the multi-threaded performance gap.

Cache hierarchies also differ. The AMD Ryzen 7 5705G has 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3 total. The Intel Core 5 221E has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache.

Memory support splits the field. The AMD processor is limited to DDR4 with dual-channel operation and a recorded memory bandwidth of 51.2 GB/s. The Intel processor handles both DDR4 and DDR5, also dual-channel, with a higher memory bandwidth of 89.6 GB/s.

PCIe connectivity differs by generation. The AMD Ryzen 7 5705G provides PCIe Gen 3 with 16 lanes from the CPU. The Intel Core 5 221E provides PCIe Gen 5 with 16 lanes from the CPU, which allows for faster peripheral bandwidth on compatible hardware.

The sockets are incompatible. The AMD Ryzen 7 5705G uses AMD Socket AM4, while the Intel Core 5 221E uses Intel Socket 1700. The AMD chip has an unlocked multiplier, while the Intel chip is locked. The Intel part also supports ECC memory, a feature absent on the AMD side.

The AMD Ryzen 7 5705G was released on 2025-02-23, and the Intel Core 5 221E was released on 2025-01-12. Both are listed as Active in production.

The Verdict

The recorded data points to a clear split between the two processors based on workload. The Intel Core 5 221E holds an 87th percentile ranking among all CPUs, while the AMD Ryzen 7 5705G sits at the 50th percentile. The Intel part also has a recorded average benchmark score of 40144, whereas the AMD part has no recorded benchmark scores in the database.

For multi-threaded productivity, the Intel Core 5 221E is the stronger option. The 14-core, 20-thread configuration delivers high scores across Cinebench and PassMark multi-thread tests. The AMD Ryzen 7 5705G, with 8 cores and 16 threads, cannot match that raw parallel throughput based on the architecture differences alone.

For single-thread responsiveness, the Intel part again leads. The boost clock of 5.20 GHz versus 4.60 GHz shows in the single-core benchmark results, where the Intel chip records strong Cinebench and PassMark single-thread scores.

The AMD Ryzen 7 5705G is not a poor performer, but the database shows no benchmark entries for it. Users who need verified performance data would look to the Intel part, which has a full suite of recorded results. The Intel Core 5 221E also offers ECC memory support and DDR5 compatibility, which matters for certain workstation or server-adjacent workloads.

For systems constrained to DDR4, the AMD part still fits that memory type, but it lacks the PCIe Gen 5 and higher memory bandwidth of the Intel chip. The AMD processor does have an unlocked multiplier, which appeals to overclocking users, but the Intel chip's locked multiplier and higher stock clocks may already provide sufficient speed.

The launch MSRP for the Intel Core 5 221E is $232. No launch MSRP is recorded for the AMD Ryzen 7 5705G.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 7 5705G and the Intel Core 5 221E. However, the Intel Core 5 221E has a full set of recorded benchmark scores that show its performance profile.

In Cinebench R23 multi-core, the Intel Core 5 221E scores 25933. Its single-core score in the same test is 3661. In Cinebench R20, multi-core is 10891 and single-core is 1537. In Cinebench R15, multi-core is 2613 and single-core is 368.

The PassMark suite adds more detail. The Intel part scores 117813 in integer math, 79028 in floating point math, and 324285 in data compression. Data encryption scores 19205, and extended instructions score 18216. The processor finds 173 prime numbers, sorts 37686 random strings, and scores 2230 in physics. Multi-thread score is 30510, and single-thread score is 4147.

Looking at the nearest rivals for the Intel Core 5 221E, the data shows a tightly clustered field. The AMD Ryzen 7 7700 scores 40081, which is 0.2% behind the Intel part. The AMD Ryzen AI 9 365 scores 40048, also 0.2% behind. The AMD Ryzen 9 270 scores 40246, which is 0.3% ahead. The Intel Core i9-13905H scores 40313, which is 0.4% ahead.

These delta percentages indicate that the Intel Core 5 221E sits within a very narrow performance band relative to those four rivals. The largest gap is only 0.4%, meaning the Intel part trades blows with recent AMD offerings in the same performance class.

For the AMD Ryzen 7 5705G, no benchmark scores are recorded, and no nearest rivals are listed. The percentile rank of 50 places it in the middle of all CPUs, but without measured scores, a direct comparison to the Intel part's 87th percentile ranking is limited to architectural inference.

The Intel Core 5 221E's multi-core scores, particularly the Cinebench R23 result of 25933, reflect the advantage of 14 cores and 20 threads. The AMD Ryzen 7 5705G's 8 cores and 16 threads would likely produce lower multi-threaded numbers, but the database does not provide those figures.

Single-thread performance favors the Intel part as well. The R23 single-core score of 3661 and PassMark single-thread score of 4147 align with the 5.20 GHz boost clock. The AMD part's 4.60 GHz boost clock suggests a lower single-thread ceiling, though no recorded score exists to confirm the gap.

The Intel part's memory bandwidth of 89.6 GB/s, double the AMD part's 51.2 GB/s, supports memory-intensive workloads. The PCIe Gen 5 interface adds further bandwidth for storage and expansion, though the AMD part's PCIe Gen 3 remains functional for standard desktop use.

The data shows the Intel Core 5 221E as a well-documented performer with strong multi-threaded results and competitive single-thread scores. The AMD Ryzen 7 5705G lacks recorded benchmarks, making its performance profile less clear in the database.
