AMD Ryzen 5 5500X3D vs Intel Core Ultra 5 245T Comparison

AMD Ryzen 5 5500X3D and Intel Core Ultra 5 245T represent two distinct approaches to desktop processing. The AMD part is a 6-core, 12-thread Zen 3 chip with a large 96 MB shared L3 cache, while the Intel part is a 14-core, 14-thread Arrow Lake chip with a smaller 24 MB L3 cache but a much higher boost clock. Benchmark data from the database reveals a clear overall winner, but the analysis of individual workloads shows where each design philosophy holds an advantage.

Head-to-Head Benchmarks

The Intel Core Ultra 5 245T dominates the head-to-head comparison, winning 10 of the 11 recorded benchmarks. The single largest margin of victory for Intel is in floating point math, where it scores 108499 against the AMD Ryzen 5 5500X3D's 34511, a delta of -68.2% from the AMD perspective. This massive gap indicates a significant architectural advantage in workloads that rely heavily on floating-point throughput.

In integer math, the Intel chip also leads decisively, scoring 88676 compared to 60033 for AMD, a performance deficit of 32.3% for the Ryzen. The pattern continues across nearly every PassMark subtest. The Intel part achieves 283812 in data compression versus 230392 for AMD, a 18.8% advantage. Data encryption shows an even larger gap, with Intel at 23656 and AMD at 13967, a 41% difference. Extended instructions results follow suit, with Intel scoring 22071 against AMD's 15925, a 27.8% lead.

The multi-threaded PassMark score strongly favors Intel: 30833 for the Core Ultra 5 245T versus 20363 for the Ryzen 5 5500X3D, a 34% difference. This is expected given the Intel part's higher core count. The single-thread score also goes to Intel, 4367 versus 2941, a 32.7% margin, reflecting the Intel chip's higher boost clock of 5.10 GHz compared to AMD's 4.00 GHz.

The random string sorting benchmark shows Intel ahead at 34931 versus 23675, a 32.2% lead. The find prime numbers test is another decisive Intel win, 324 versus 170, a 47.5% difference. The only benchmark where AMD claims victory is the PassMark physics test, scoring 2282 against Intel's 2278. This is an extremely narrow margin, only a 0.2% difference, but it is a win nonetheless. These results indicate that while the Intel chip is faster in almost every measurable category, the AMD part holds a slight edge in this specific physics simulation workload.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 5 5500X3D is based on the Zen 3 architecture, codenamed Vermeer, and is manufactured on a 7 nm process at TSMC. The Intel Core Ultra 5 245T uses the Arrow Lake architecture, codenamed Arrow Lake-S, and is built on a more advanced 3 nm process, also from TSMC. This process node difference likely contributes to the Intel chip's higher efficiency and clock speeds.

Core configuration is a major differentiator. The AMD processor has 6 cores and 12 threads, while the Intel processor has 14 cores and 14 threads. The Intel chip lacks hyper-threading, as its thread count equals its core count, whereas the AMD chip uses simultaneous multithreading to double its thread count. This means the Intel part relies on its higher physical core count for multi-threaded performance, while the AMD part uses its thread scheduling to improve utilization.

Cache hierarchy differs significantly between the two. The AMD Ryzen 5 5500X3D features 64 KB of L1 cache and 512 KB of L2 cache per core, with a massive 96 MB of shared L3 cache. The Intel Core Ultra 5 245T has 192 KB of L1 cache and 3 MB of L2 cache per core, with only 24 MB of shared L3 cache. The AMD chip's large L3 cache is a defining feature of the X3D series, designed to reduce memory latency in gaming and other cache-sensitive workloads.

Memory support also diverges. The AMD processor supports DDR4 memory with a dual-channel bus, providing 51.2 GB/s of bandwidth. The Intel processor supports DDR5 memory with a dual-channel bus, providing 102.4 GB/s of bandwidth. This doubles the theoretical memory bandwidth for the Intel part, which can benefit memory-intensive applications. Both processors support ECC memory.

The platform and connectivity differ as well. The AMD Ryzen 5 5500X3D uses the AMD Socket AM4 and provides PCIe Gen 4 with 20 lanes from the CPU. The Intel Core Ultra 5 245T uses the Intel Socket 1851 and provides PCIe Gen 5 with 20 lanes from the CPU. The Intel chip also includes integrated graphics, an Arc Xe-LPG Graphics 64EU unit, while the AMD chip has no integrated graphics. The Intel part has a die size of 243 mm² and contains 17,800 million transistors, while the AMD part has a die size of 74 mm².

Where Each One Wins

The Intel Core Ultra 5 245T is the clear winner in compute-heavy tasks. Its performance in floating point math, with a score of 108499, is more than three times that of the AMD part, indicating a strong advantage in scientific computing, simulations, and any workload that processes large amounts of fractional numbers. The 32.3% lead in integer math also positions it well for general-purpose programming, data processing, and encryption tasks. The 34% lead in the PassMark multi-thread score means the Intel chip is better suited for video encoding, 3D rendering, and other parallel workloads that can utilize its 14 physical cores.

The AMD Ryzen 5 5500X3D, despite losing most benchmarks, has its niche. Its only win in the physics test, albeit by a tiny 0.2% margin, suggests it may have a slight advantage in specific physics calculations. More importantly, its large 96 MB L3 cache is a feature designed for gaming and other latency-sensitive applications, even though the database does not include a dedicated gaming test. The AMD chip also consumes less power, with a TDP of 105 W compared to Intel's 65 W, which is a notable difference. The Intel chip is actually the lower-power part despite having more cores and higher clock speeds.

The Intel Core Ultra 5 245T also wins decisively in single-thread performance, scoring 4367 versus 2941, a 32.7% margin. This is critical for applications that rely on a single core, such as many older games and certain productivity tools. The higher boost clock of 5.10 GHz compared to 4.00 GHz is the primary driver of this advantage.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 5 5500X3D has 6 cores and 12 threads, while the Intel Core Ultra 5 245T has 14 cores and 14 threads. Base clocks are 3.00 GHz for AMD and 2.20 GHz for Intel, but boost clocks are 4.00 GHz for AMD and 5.10 GHz for Intel. The Intel chip has a higher TDP at 65 W, while the AMD chip is rated at 105 W.

The process node differs, with AMD on 7 nm and Intel on 3 nm. The AMD chip has a die size of 74 mm², while the Intel chip is much larger at 243 mm². The Intel chip also has a transistor count of 17,800 million, a figure not listed for the AMD part. Cache configurations are distinct: AMD has 64 KB L1 and 512 KB L2 per core, with 96 MB shared L3; Intel has 192 KB L1 and 3 MB L2 per core, with 24 MB shared L3.

Memory support is a key difference: AMD uses DDR4 with 51.2 GB/s bandwidth, Intel uses DDR5 with 102.4 GB/s bandwidth. The PCIe interface differs, with AMD providing Gen 4 and Intel providing Gen 5, both with 20 lanes. The AMD chip has no integrated graphics, while the Intel chip includes Arc Xe-LPG Graphics 64EU. The sockets are incompatible, with AMD using Socket AM4 and Intel using Socket 1851. The release dates also differ, with AMD launched on 2025-06-04 and Intel on 2025-01-06. The Intel part has a launch MSRP of $270, while the AMD part has no listed launch MSRP.
