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

The Intel Core i7-1255U and AMD Ryzen 3 PRO 8300G occupy different positions in the performance spectrum, despite both registering at the 71st percentile among all CPUs in the database. The Intel part, a mobile Alder Lake-U processor, posts an average benchmark score of 17,656, while the AMD desktop Zen 4 chip scores 17,278. Their head-to-head record shows the AMD winning 11 of 17 benchmarks, but the Intel taking decisive victories in several specific workloads. The data indicates that these are not direct competitors in the traditional sense; rather, they are optimized for different task categories, with the Intel excelling in legacy and math-heavy single-threaded tests and the AMD dominating in modern multi-threaded rendering and instruction-heavy workloads.

Where Each One Wins

The AMD Ryzen 3 PRO 8300G claims a clear lead in modern multi-core rendering tasks. In Cinebench R23 multicore, it scores 12,359 against the Intel's 8,285, a 33% advantage. This trend continues in Cinebench R20 multicore, where the AMD scores 5,190 versus 4,635, a 10.7% margin. The AMD also wins in Cinebench R23 single-core with a score of 1,744 compared to 1,647, and in Cinebench R20 single-core with 732 versus 654, both at 5.6% and 10.7% deltas respectively. For users running current-generation rendering software, the AMD is the stronger choice.

The Intel Core i7-1255U takes the crown in specific mathematical and legacy workloads. Its most significant win is in PassMark floating point math, scoring 32,618 against the AMD's 23,374, a massive 39.5% advantage. It also leads in integer math with 48,498 versus 37,292, a 30% gap. In Cinebench R15, the older test version, the Intel wins both multicore (1,387 vs 1,245, 11.4% ahead) and single-core (237.5 vs 175, 35.7% ahead). The Intel also wins in data encryption (9,262 vs 8,607) and physics (789 vs 772). These results suggest the Intel architecture retains an edge in older instruction paths and pure arithmetic throughput.

The AMD dominates in instruction-heavy and sorting workloads. It scores 11,451 in PassMark extended instructions versus 8,231, a 28.1% lead, and 19,703 in random string sorting versus 16,934, a 14.1% advantage. The AMD also wins in prime number finding (47 vs 40) and data compression (150,567 vs 147,320). The multithread score is nearly tied, with the AMD at 13,368 and Intel at 13,234, a 1% difference. The single-thread PassMark test goes to the AMD at 3,550 versus 3,192, a 10.1% margin.

Architecture Differences

The fundamental architecture gap is stark. The Intel Core i7-1255U is built on Alder Lake-U using Intel's 10 nm process, featuring a hybrid core design with 10 cores and 12 threads. The AMD Ryzen 3 PRO 8300G uses Zen 4 architecture on TSMC's 4 nm process, with a traditional 4-core, 8-thread layout. The process node difference is significant: 10 nm versus 4 nm, and the foundry shifts from Intel to TSMC. The AMD chip has 20,900 million transistors on a 137 mm² die, while the Intel's transistor count and die size are not recorded in the database.

Cache configurations differ substantially. The Intel provides 80 KB of L1 per core and 1.25 MB of L2 per core, with 12 MB of shared L3. The AMD offers 64 KB L1 per core and 1 MB L2 per core, with only 8 MB of shared L3. Despite having fewer cores, the AMD's smaller cache per core is offset by its higher clock speeds. The Intel has a base clock of 1.70 GHz and a boost of 4.70 GHz, while the AMD runs at a base of 3.40 GHz and boosts to 4.90 GHz. The AMD's higher base clock is more than double the Intel's, which is typical for a desktop part versus a low-power mobile processor.

Memory support diverges as well. The Intel supports both DDR4 and DDR5 in dual-channel mode, while the AMD supports only DDR5 and has a recorded memory bandwidth of 83.2 GB/s. The Intel's memory bandwidth is not listed. ECC memory is supported by the AMD but not the Intel. PCIe lanes also differ: the Intel provides 20 Gen 4 lanes (CPU only), while the AMD provides 14 Gen 4 lanes. Integrated graphics are the Iris Xe 96EU on the Intel and the Radeon 740M on the AMD.

The socket and market segment reinforce their different roles. The Intel uses Intel BGA 1744 and is a mobile part, while the AMD uses the AM5 socket and is a desktop processor. The thermal design power (TDP) reflects this: the Intel is rated at 15 W, the AMD at 65 W. The AMD was released on April 15, 2024, while the Intel came out on February 22, 2022. Neither chip has a recorded launch MSRP, and neither has an unlocked multiplier.

FAQ

Q: Which processor has more cores and threads?

A: The Intel Core i7-1255U has 10 cores and 12 threads, while the AMD Ryzen 3 PRO 8300G has 4 cores and 8 threads. The Intel provides two extra threads despite having six more cores, a result of its hybrid Alder Lake design.

Q: Why does the AMD win in Cinebench R23 multicore despite having fewer cores?

A: The AMD scores 12,359 versus 8,285 in Cinebench R23 multicore, a 33% advantage.

Head-to-Head Benchmarks

The biggest win for the Intel is in PassMark floating point math. The Intel scores 32,618, the AMD scores 23,374, giving the Intel a 39.5% advantage. This is followed by the Cinebench R15 single-core result, where the Intel scores 237.5 versus 175, a 35.7% lead. In integer math, the Intel again wins by a wide margin: 48,498 versus 37,292, a 30% difference. The Intel also wins in data encryption (9,262 vs 8,607, 7.6% ahead), Cinebench R15 multicore (1,387 vs 1,245, 11.4% ahead), and physics (789 vs 772, 2.2% ahead).

The AMD's largest victory is in Cinebench R23 multicore, where it scores 12,359 against the Intel's 8,285, a 33% margin. This is the single biggest absolute score gap in the comparison. The AMD also wins by 28.1% in PassMark extended instructions (11,451 vs 8,231) and by 14.1% in random string sorting (19,703 vs 16,934). In Cinebench R20, the AMD leads in both multicore (5,190 vs 4,635) and single-core (732 vs 654), each by 10.7%. The AMD wins PassMark single-thread with 3,550 versus 3,192, a 10.1% edge, and prime number finding with 47 versus 40, a 14.9% margin. Data compression goes to the AMD at 150,567 versus 147,320, a 2.2% difference, and multithread goes to the AMD at 13,368 versus 13,234, a 1% margin.

The pattern shows the Intel pulling ahead in older Cinebench R15 tests and in pure math workloads, while the AMD excels in the more recent Cinebench R20 and R23 versions, which are better optimized for modern instruction sets. The near-tie in multithread and the AMD's win in single-thread suggest that for general productivity, the AMD is slightly faster, but the Intel's 10-core design still competes effectively in mixed workloads. The recorded data indicates a 6-win, 11-win split in favor of the AMD, but the Intel's wins tend to be larger in percentage terms, particularly in floating point and integer math.
