The Verdict

The data presents a fascinating split. The AMD Ryzen 3 PRO 8300GE wins more benchmarks overall (10 wins versus 7), but the Intel Core i7-1355U wins the biggest single margin. If your workload is heavily multi-threaded and scales well with cores, the Intel part's 10 cores and 12 threads give it a structural advantage in certain tasks, like floating-point math where it leads by 38.4%. However, the AMD chip's Zen 4 architecture, despite having only 4 cores, delivers superior results in Cinebench R20 and R23 multi-core tests, suggesting better per-core efficiency and possibly better thermal behavior under sustained load.

For users running modern rendering workloads like Cinebench R23, the AMD Ryzen 3 PRO 8300GE is the stronger choice by a wide margin. For users who need broad integer math performance or data encryption, the Intel Core i7-1355U is more compelling. The AMD part also offers ECC memory support and a desktop socket (AM5), which may be decisive for workstation builds. The Intel part is a mobile chip (BGA 1744) with a 15W TDP, making it suitable for thin-and-light laptops, while the AMD chip's 35W TDP and desktop socket target a different class of machine.

Head-to-Head Benchmarks

The benchmark data reveals a clear pattern: the AMD Ryzen 3 PRO 8300GE dominates in modern Cinebench versions, while the Intel Core i7-1355U excels in PassMark math workloads. The biggest win for AMD is in Cinebench R23 multi-core, where it scores 12511 versus 8286, a 33.8% lead. That is a massive gap, especially considering the AMD chip has only 4 cores.

Intel's largest victory comes in PassMark floating-point math, where it scores 34965 against AMD's 25258, a 38.4% advantage. The Intel chip also wins PassMark integer math by 28.9% (52002 versus 40348). These math-heavy results indicate that the Intel chip's 10 cores can be fully utilized in parallel arithmetic operations.

The Cinebench R15 results also favor Intel, with a 10.6% multi-core win (1393 versus 1260) and a striking 44.4% single-core win (255.5 versus 177). That single-core R15 delta is the second-largest in the entire comparison, suggesting Intel's architecture has a significant edge in older, less optimized workloads.

AMD strikes back in Cinebench R20, winning multi-core by 5.8% (5254 versus 4949) and single-core by 5.8% (741 versus 698). The trend from R15 to R20 to R23 shows AMD's advantage growing with each newer version of the benchmark, which implies better optimization for modern instruction sets and memory access patterns.

PassMark results are mixed. AMD wins data compression by 4.2% (162623 versus 155727), random string sorting by 12.4% (20134 versus 17631), and single-thread by 10% (3828 versus 3444). Intel wins data encryption by 6.6% (9831 versus 9224) and physics by 3.6% (888 versus 857). The PassMark multithread score is nearly identical, with AMD leading by just 0.7% (14403 versus 14299).

The extended instructions workload shows AMD's strength, winning by 29.1% (12313 versus 8726). This indicates the AMD chip handles SIMD and other extended instruction sets more efficiently, which could translate to better performance in scientific and media applications.

Specification Differences

The two processors differ in nearly every fundamental specification. The Intel Core i7-1355U has 10 cores and 12 threads, while the AMD Ryzen 3 PRO 8300GE has 4 cores and 8 threads. Intel's base clock is 1700 MHz with a boost of 5.00 GHz, while AMD's base clock is higher at 3.40 GHz but boosts to 4.90 GHz. The Intel chip has a 15W TDP, whereas the AMD chip has a 35W TDP.

Socket compatibility is entirely different: Intel uses BGA 1744 (mobile), while AMD uses Socket AM5 (desktop). Memory support diverges as well, with Intel supporting DDR4 and DDR5, while AMD supports only DDR5. AMD has a memory bandwidth of 83.2 GB/s, while Intel's bandwidth is not listed. ECC memory is supported on AMD but not on Intel.

PCIe lanes differ, with Intel offering Gen 4, 8 lanes (CPU only), and AMD offering Gen 4, 14 lanes (CPU only). The process node is another major difference: Intel uses 10 nm from its own foundry, while AMD uses 4 nm from TSMC. AMD's transistor count is 20,900 million with a die size of 137 mm², while Intel's transistor count and die size are not listed.

Cache configurations are also distinct. Intel has 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3. AMD has 64 KB L1 per core, 1 MB L2 per core, and 8 MB shared L3. The integrated graphics differ, with Intel using Iris Xe Graphics 96EU and AMD using Radeon 740M.

Architecture Differences

The architectural divide is stark. Intel's Core i7-1355U is built on Raptor Lake, specifically the Raptor Lake-U codename, using Intel's 10 nm process. AMD's Ryzen 3 PRO 8300GE uses Zen 4 architecture with the Phoenix2 codename, fabricated on TSMC's 4 nm process. This process advantage gives AMD a significant transistor density benefit, with 20,900 million transistors packed into 137 mm².

The core count difference (10 for Intel versus 4 for AMD) is partially offset by AMD's higher base clock (3.4 GHz versus 1.7 GHz) and nearly identical boost clock (4.9 GHz versus 5.0 GHz). AMD's per-core L2 cache is 1 MB, which is smaller than Intel's 1.25 MB per core, but AMD's shared L3 is 8 MB versus Intel's 12 MB. The per-core L1 cache favors Intel (80 KB versus 64 KB).

The memory architecture also differs. AMD supports only DDR5 with a dual-channel bus and a specified bandwidth of 83.2 GB/s, while Intel supports both DDR4 and DDR5 with dual-channel bus but no listed bandwidth. AMD's ECC support suggests a focus on workstation reliability. The PCIe configuration favors AMD with 14 lanes versus Intel's 8 lanes, both at Gen 4 speeds.

The market segments are completely different: Intel is a mobile processor (BGA 1744 socket), while AMD is a desktop processor (AM5 socket). The release dates also differ, with Intel launching on 2023-01-03 and AMD on 2024-04-15. Intel's part number is SRMLY, while AMD's is 100-000001189.

Where Each One Wins

The Intel Core i7-1355U wins decisively in older Cinebench R15 tests, both multi-core (10.6% ahead) and single-core (44.4% ahead). It also wins Cinebench R23 single-core by 3.3%. In PassMark workloads, Intel dominates floating-point math (38.4% ahead), integer math (28.9% ahead), data encryption (6.6% ahead), and physics (3.6% ahead). These wins suggest Intel's 10-core design excels at parallel arithmetic, cryptographic operations, and physics simulations. If your workload involves number crunching, rendering in older software, or encryption-heavy tasks, the Intel chip is the data-driven choice.

The AMD Ryzen 3 PRO 8300GE wins in modern Cinebench R20 and R23 multi-core tests, with its R23 multi-core lead of 33.8% being the standout result. It also wins in PassMark data compression (4.2% ahead), extended instructions (29.1% ahead), random string sorting (12.4% ahead), single-thread (10% ahead), and multithread (0.7% ahead). The AMD chip's wins are concentrated in newer benchmarks and specialized instruction workloads. For users running current rendering engines, compression tools, or SIMD-heavy applications, the AMD chip is clearly superior.

The PassMark multithread result is nearly a tie (14403 versus 14299), indicating that for general multi-threaded productivity, both chips perform similarly. The find prime numbers test is also a near tie (52 versus 51). The data implies that the AMD chip's efficiency per core compensates for its lower core count in most modern workloads, while the Intel chip's raw core count wins in older and math-heavy tasks. The choice ultimately depends on whether your software leverages modern instruction sets (AMD wins) or relies on legacy single-thread performance and parallel integer math (Intel wins).
