AMD Ryzen 3 8300G vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive sweep for the Intel Core Ultra 5 225T across every recorded test, with 17 wins out of 17 comparisons. The AMD Ryzen 3 8300G does not claim a single head-to-head victory, and the margins vary widely depending on the workload type.

The largest gap appears in prime number finding, where the Intel part scores 284 versus 47 for the AMD chip, a delta of -83.5% from the AMD perspective. That means the Intel processor delivers roughly six times the throughput in this highly iterative integer workload. Floating point math shows a similarly lopsided result: 82,751 for Intel versus 25,336 for AMD, a -69.4% delta. Physics simulation also favors Intel heavily at 2,053 versus 755, a -63.2% gap, which suggests the Intel part has substantially more headroom for constraint-based and rigid-body computations.

Single-thread performance is the closest contest. In PassMark single-thread, Intel scores 4,348 against AMD's 3,778, a -13.1% delta. Cinebench R23 single-core shows Intel at 3,101 versus 1,724, a -44.4% delta, which is a much wider spread than the PassMark single-thread result. This discrepancy indicates that the Intel architecture responds differently to the Cinebench rendering workload than to PassMark's synthetic mix.

Multi-threaded tests follow a consistent pattern. Cinebench R23 multi-core scores 21,971 for Intel versus 12,217 for AMD, a -44.4% delta. Cinebench R20 multi-core shows 9,227 versus 5,131, also -44.4%. The R15 multi-core test lands at 2,214 versus 1,231, again -44.4%. PassMark multithread shows 25,358 versus 14,018, a -44.7% delta. The consistency of the Cinebench deltas at -44.4% across all three versions suggests a stable performance ratio in rendering workloads, independent of the benchmark iteration.

Data compression and encryption show moderate gaps. Compression scores 233,998 for Intel versus 158,952 for AMD, a -32.1% delta. Encryption scores 18,289 versus 9,115, a -50.2% delta, meaning Intel more than doubles AMD's encryption throughput. Extended instructions score 20,083 versus 12,354, a -38.5% delta. Integer math scores 59,543 versus 40,534, a -31.9% delta, while random string sorting scores 28,774 versus 19,013, a -33.9% delta.

The overall average benchmark score confirms the hierarchy. Intel's average is 30,468, placing it in the 82nd percentile among all CPUs in the database. AMD's average is 18,169, placing it in the 72nd percentile. The nearest rivals for Intel include the Core i9-11980HK (30,422, delta +0.2%), the Ryzen 5 7640HS (30,390, +0.3%), the Core i5-13600H (30,548, -0.3%), and the Ryzen 7 7736U (30,364, +0.3%). AMD's nearest rivals include the Ryzen 7 5700U (18,176, delta 0%), the Core i7-1365U (18,177, 0%), the Core i7-9700 (18,180, -0.1%), and the Core i5-1334U (18,154, +0.1%). Both chips sit within a very tight cluster of similar-performing parts, but the clusters themselves are far apart.

Where Each One Wins

The Intel Core Ultra 5 225T wins every recorded workload category, so the use-case split is one-sided based on the data. The strongest Intel advantages appear in floating point math, prime number finding, and physics simulation, where deltas range from -63.2% to -83.5%. These workloads benefit from the Intel part's higher core count and larger cache allocation, and the results suggest a clear edge for scientific computing, financial modeling, and physics-based rendering.

The Intel part also dominates rendering workloads, as shown by the consistent -44.4% delta across all Cinebench multi-core and single-core versions. This makes it the stronger choice for 3D modeling, video encoding, and any production task that relies on Cinebench-style ray tracing or shading calculations. Data encryption, with a -50.2% delta, points to a meaningful advantage in security-related tasks, disk encryption, and VPN throughput.

The AMD Ryzen 3 8300G does not win any benchmark, but its closest relative performance comes in PassMark single-thread at -13.1%. That means in lightly threaded office productivity, web browsing, and general desktop responsiveness, the AMD part is closer to Intel's level, though still behind. The AMD chip also has a lower average benchmark score of 18,169 versus 30,468, so it occupies a different performance tier entirely.

For users prioritizing multithreaded throughput, the Intel part delivers 25,358 in PassMark multithread versus 14,018 for AMD, a -44.7% delta. For integer math, Intel scores 59,543 versus 40,534, a -31.9% delta, which is a smaller but still substantial gap. Random string sorting shows 28,774 versus 19,013, a -33.9% delta. These results indicate that the Intel part is the better choice for database operations, sorting algorithms, and general integer-heavy code.

Specification Differences

The two processors differ in nearly every fundamental specification. The AMD Ryzen 3 8300G has 4 cores and 8 threads, while the Intel Core Ultra 5 225T has 10 cores and 10 threads, meaning Intel offers more physical cores but no hyper-threading. Both boost to 4.90 GHz, but the AMD base clock is 3.40 GHz versus Intel's 2.50 GHz.

Cache configurations diverge sharply. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 8 MB shared L3. Intel uses 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3. The Intel part has substantially more L3 cache, which helps explain its lead in cache-sensitive workloads like data compression.

Memory bandwidth also favors Intel. Both support DDR5 and dual-channel memory, but Intel's bandwidth is rated at 102.4 GB/s versus AMD's 83.2 GB/s. AMD supports ECC memory while Intel does not. PCIe connectivity differs as well: AMD offers Gen 4 with 14 lanes, while Intel offers Gen 5 with 20 lanes.

The integrated graphics are different. AMD uses Radeon 740M, while Intel uses Arc Xe-LPG Graphics 16EU. Both processors are desktop parts, both are currently active in production, and both have locked multipliers, so neither supports overclocking via multiplier changes.

The AMD chip was released on 2024-01-07 and has a launch MSRP of $176. The Intel chip was released on 2024-12-31 and has no recorded launch MSRP in the database. The AMD part number is 100-000001492, while Intel's part number is listed as unknown.

Architecture Differences

The AMD Ryzen 3 8300G uses the Zen 4 architecture with the Phoenix2 codename, built on TSMC's 4 nm process. The Intel Core Ultra 5 225T uses the Arrow Lake architecture with the Arrow Lake-S codename, built on TSMC's 3 nm process. The smaller process node gives Intel a transistor density advantage despite having fewer transistors overall: Intel packs 17,800 million transistors into a 243 mm² die, while AMD packs 20,900 million transistors into a 137 mm² die. The AMD die is smaller and denser, but the Intel die has more physical area for cache and other logic.

The core designs differ fundamentally. AMD uses 4 cores with 8 threads, relying on simultaneous multithreading to extract parallelism. Intel uses 10 cores with 10 threads, no SMT, but a higher physical core count. The Intel L2 cache per core is 3 MB versus AMD's 1 MB, and the L3 cache is 20 MB shared versus 8 MB shared. These cache differences likely contribute to Intel's lead in memory-heavy workloads like compression and encryption.

Socket and platform support also differ. AMD uses Socket AM5, while Intel uses Socket 1851. Both support DDR5 memory and dual-channel operation, but Intel's memory bandwidth is higher. AMD supports ECC memory, which is relevant for workstation or server-adjacent use cases. Intel's PCIe implementation is newer (Gen 5 versus Gen 4) and offers more lanes (20 versus 14), which matters for high-throughput expansion cards and storage devices.

The integrated graphics solutions are architecturally distinct as well. AMD pairs its Zen 4 cores with Radeon 740M graphics, while Intel pairs its Arrow Lake cores with Arc Xe-LPG Graphics 16EU. The benchmark data does not include iGPU-specific tests, so the relative graphics performance is not quantified in the database. Both chips target the desktop segment, and both are listed as active production parts. The Intel part's release date is later by nearly a year, which aligns with its newer architecture and process node.
