AMD Ryzen 3 8300GE vs Intel Core i7-1255U Comparison

The Intel Core i7-1255U and AMD Ryzen 3 8300GE are two very different processors that land at nearly the same overall performance tier, with average benchmark scores of 17656 and 17614 respectively. The Intel part wins 6 of 17 head-to-head tests, while the AMD chip wins 11. The Core i7-1255U is a mobile processor built on Intel's 10 nm Alder Lake-U architecture, featuring 10 cores and 12 threads with a 15 W TDP, designed for thin-and-light laptops. The Ryzen 3 8300GE is a desktop chip on AMD's 4 nm Zen 4 Phoenix2 architecture, with 4 cores and 8 threads at a 35 W TDP, aimed at compact desktop systems. The data shows that the AMD chip is the stronger overall performer, particularly in sustained multi-threaded workloads and single-thread throughput, while the Intel chip counters with significant wins in floating-point math, integer math, and encryption. The choice between them hinges on platform and workload: the Ryzen 3 8300GE offers a more modern node and faster single-core performance, whereas the Core i7-1255U brings a higher core count and specific computational strengths.

The Verdict

From the benchmark data, the AMD Ryzen 3 8300GE is the clear pick for users prioritizing raw multi-core rendering and general desktop throughput. Its Cinebench R23 multicore score of 11705 is a massive 29.2% ahead of the Intel Core i7-1255U’s 8285, and it also leads in PassMark single-thread performance by 12.4% (3644 vs 3192). The Ryzen 3 8300GE also wins in extended instructions (11923 vs 8231, a 31% advantage) and data compression (155164 vs 147320). This makes it the better choice for content creation, compilation, and any task that scales with sustained multi-core execution.

The Intel Core i7-1255U is the pick for specific computational niches. It dominates floating-point math with a score of 32618, which is 32.2% higher than the Ryzen’s 24681, and leads integer math by 23.8% (48498 vs 39163). It also wins data encryption by 7.7% (9262 vs 8603) and physics by 5.2% (789 vs 750). If a workload is heavily math-oriented or encryption-bound, the Intel chip is the superior engine despite its overall lower aggregate score.

However, the overall average scores are nearly identical (17656 vs 17614, a 0.2% difference favoring Intel), placing both at the 71st percentile of all CPUs. The Ryzen 3 8300GE wins 11 of 17 tests, but the Intel part’s wins are often by larger margins, creating a nuanced picture. For a general-purpose desktop build, the Ryzen 3 8300GE is the safer recommendation due to its lead in the most common multi-threaded and single-threaded benchmarks. For a mobile platform where the 15 W TDP of the Intel chip is a decisive advantage, the Core i7-1255U is the only option in this comparison, given the Ryzen 3 8300GE is a desktop part.

Architecture Differences

The two processors are built on fundamentally different design philosophies and manufacturing processes. The Intel Core i7-1255U uses the Alder Lake-U architecture, manufactured on Intel’s 10 nm process, and features a hybrid core layout with 10 cores and 12 threads. The AMD Ryzen 3 8300GE uses the Zen 4 architecture with the Phoenix2 codename, built on TSMC’s 4 nm process, with 4 cores and 8 threads. The process node difference is significant: 10 nm for Intel versus 4 nm for AMD, which contributes to the AMD chip’s higher base clock of 3.50 GHz versus Intel’s 1.70 GHz, and a boost clock of 4.90 GHz versus 4.70 GHz.

Cache configurations also differ notably. The Intel chip has a larger L3 cache at 12 MB shared, compared to 8 MB shared on the AMD chip. However, the AMD chip uses smaller per-core L1 and L2 caches: 64 KB and 1 MB per core respectively, versus Intel’s 80 KB and 1.25 MB per core. The AMD chip includes ECC memory support, which the Intel chip lacks. Memory support diverges as well: the Intel part supports both DDR4 and DDR5, while the AMD part only supports DDR5, but with a higher rated memory bandwidth of 83.2 GB/s compared to no listed bandwidth for Intel.

The integrated graphics differ: Intel uses Iris Xe 96EU, while AMD uses Radeon 740M. The platform sockets are incompatible: Intel BGA 1744 for the mobile chip versus AMD Socket AM5 for the desktop chip. The AMD chip has a much higher transistor count at 20,900 million and a die size of 137 mm², while those details are not listed for Intel. PCIe support also differs, with Intel offering Gen 4 with 20 lanes and AMD offering Gen 4 with 14 lanes. The AMD chip uses a dual-channel memory bus, as does Intel, but the AMD chip’s memory bandwidth is explicitly rated higher. Production status is Active for both, with the Intel release date in 2022-02-22 and the AMD release date in 2024-04-15.

Head-to-Head Benchmarks

The most decisive victory for the AMD Ryzen 3 8300GE comes in Cinebench R23 multicore, where it scores 11705 against Intel’s 8285, a 29.2% lead. This is the single largest delta in the entire comparison and indicates a substantial advantage in sustained multi-threaded rendering. The AMD chip also wins Cinebench R20 multicore by 5.7% (4916 vs 4635) and R20 single-core by 5.6% (693 vs 654). In PassMark single-thread, the AMD chip leads by 12.4% (3644 vs 3192), showing better per-core efficiency. The AMD chip also wins in extended instructions by 31% (11923 vs 8231) and data compression by 5.1% (155164 vs 147320).

The Intel Core i7-1255U counters with its largest win in floating-point math, scoring 32618 versus 24681, a 32.2% advantage. Integer math also favors Intel by 23.8% (48498 vs 39163). Data encryption goes to Intel by 7.7% (9262 vs 8603). Intel also wins Cinebench R15 multicore by 17.6% (1387 vs 1179) and R15 single-core by 43.1% (237.5 vs 166). The physics test goes to Intel by 5.2% (789 vs 750). PassMark multithread is close, with AMD winning by 2% (13507 vs 13234), and random string sorting goes to AMD by 6% (18010 vs 16934). The find prime numbers test is a narrow AMD win at 9.1% (44 vs 40). Cinebench R23 single-core is essentially tied, with AMD winning by only 0.3% (1652 vs 1647).

The pattern is clear: AMD wins the modern, heavily multi-threaded workloads (R23 multicore) and single-thread throughput, while Intel wins older Cinebench versions and math-intensive PassMark tests. The Intel chip’s 10-core configuration gives it an edge in R15 multicore, but the AMD chip’s Zen 4 architecture proves superior in R20 and R23 multicore, suggesting better scaling and IPC.
