AMD Ryzen 5 9500F vs Intel Core Ultra 5 245K Comparison

The Verdict

The data presents a clear performance hierarchy between these two desktop processors. The Intel Core Ultra 5 245K wins every single head-to-head benchmark in the fact pack, taking all 11 tests. Its average benchmark score of 54053 sits 2.2% above the AMD Ryzen 5 9500F’s 52873. Both chips occupy the same 91st percentile among all CPUs, meaning they are both strong performers, but the Intel part consistently outpaces its rival across every measured workload.

For a user focused purely on raw performance metrics, the Intel Core Ultra 5 245K is the choice. It leads in multi-threaded work by 52%, in floating-point math by 131%, and in data encryption by 111.8%. However, the AMD Ryzen 5 9500F is not without merit. It achieves this level of performance with a 65W TDP compared to Intel’s 125W TDP, uses 6 cores versus 14, and still lands in the same 91st percentile. The AMD part is for the user who prioritizes efficiency and platform simplicity (no integrated graphics, but also lower power draw) while accepting a measurable performance deficit. The Intel part is for the user who wants the maximum score in every category listed, regardless of power consumption or core count.

Architecture Differences

The two CPUs come from fundamentally different design philosophies. The Intel Core Ultra 5 245K is built on Arrow Lake, part of the Core Ultra Series 2, and uses a 3 nm process node from TSMC. It packs 14 cores and 14 threads, with no hyper-threading. The AMD Ryzen 5 9500F is a Zen 5 part from the 9000 series, built on Granite Ridge, using a 4 nm process node, also from TSMC. It has 6 cores and 12 threads, leveraging simultaneous multi-threading.

The transistor counts tell a story of scale. Intel’s chip contains 17,800 million transistors on a 243 mm² die, while AMD’s has 8,315 million transistors on a much smaller 70.6 mm² die. The cache hierarchies also differ. Intel uses 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. AMD uses 80 KB of L1 per core, 1 MB of L2 per core, and a larger 32 MB of shared L3. The shared L3 advantage for AMD (32 MB vs 24 MB) does not translate into benchmark wins in this data, however.

Feature-wise, the Intel chip includes integrated Arc Xe-LPG Graphics with 64 execution units, while the AMD chip has no integrated graphics at all. Both support DDR5 memory and dual-channel buses, but Intel’s memory bandwidth is rated at 102.4 GB/s versus AMD’s 89.6 GB/s. Intel also has a higher boost clock at 5.20 GHz compared to AMD’s 5.00 GHz. Both are unlocked for overclocking, and both support ECC memory. The sockets are incompatible: Intel Socket 1851 versus AMD Socket AM5. Intel’s PCIe is Gen 5 with 20 lanes (CPU only), while AMD offers Gen 5 with 24 lanes (CPU only). The release dates differ significantly, with Intel launching on 2024-10-23 and AMD on 2025-09-07.

Head-to-Head Benchmarks

The benchmark data is unambiguous: Intel wins every single comparison. The largest margin comes in floating-point math, where Intel scores 130678 against AMD’s 56570, a 131% advantage. This is a massive gap, suggesting Intel’s execution units handle this workload far more efficiently. Data encryption also shows a huge divide: Intel’s 33286 versus AMD’s 15716, a 111.8% lead. For users doing encryption-heavy tasks, this is a decisive factor.

Multi-threaded performance is another clear Intel victory. The passmark_multithread score for Intel is 43047, while AMD manages 28312, a 52% difference. This aligns with the core count disparity (14 vs 6), but the margin is larger than the raw core ratio would suggest, indicating strong scaling on Intel’s part. The physics test tells a similar story: Intel scores 3081, AMD scores 1851, a 66.5% lead for Intel.

Not every win is as dramatic. In integer math, Intel leads by only 17%, scoring 98524 versus 84198. This is the closest margin in the entire dataset, suggesting that AMD’s Zen 5 cores are competitive in this specific integer workload. Single-thread performance is also relatively close: Intel scores 4714, AMD scores 4258, a 10.7% lead for Intel. This indicates that Intel’s higher boost clock (5.20 GHz vs 5.00 GHz) and architecture provide a modest but consistent single-thread advantage.

Other tests show intermediate gaps. Data compression: Intel 458817, AMD 325678, a 40.9% lead. Extended instructions: Intel 37617, AMD 26370, a 42.7% lead. Random string sorting: Intel 55098, AMD 34174, a 61.2% lead. Find prime numbers: Intel 414, AMD 220, an 88.2% lead. In every case, the Intel part is ahead, and often by a substantial margin.

Where Each One Wins

The Intel Core Ultra 5 245K wins everywhere in the benchmark data. It takes all 11 head-to-head tests, with wins ranging from 10.7% in single-thread to 131% in floating-point math. For any workload measured here — data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithreaded tasks, physics, random string sorting, or single-threaded tasks — the Intel part is the faster choice. Its 14 cores and 14 threads provide a foundation for heavy parallel workloads, and its higher clocks (base 4.20 GHz, boost 5.20 GHz) support strong single-thread performance.

The AMD Ryzen 5 9500F does not win a single benchmark in this comparison. However, its wins are contextual, not numeric. It achieves a similar overall percentile ranking (91st) with half the core count and nearly half the TDP (65W vs 125W). Its smaller die size (70.6 mm² vs 243 mm²) and lower transistor count (8,315 million vs 17,800 million) suggest better efficiency per transistor. For users building a system where power draw is a constraint, or where the lack of integrated graphics is acceptable (or even preferred, for dedicated GPUs), the AMD part offers a path to 91st-percentile performance with less energy consumption. The Intel part is for pure performance, and the AMD part is for efficiency-minded builds that can accept a 10-50% performance hit in most measured areas.
