AMD Ryzen 7 9700X vs Intel Core Ultra 5 245T Comparison

The Intel Core Ultra 5 245T and AMD Ryzen 7 9700X are both 65W desktop processors aimed at mainstream builds, but they take very different approaches to achieving performance. The data shows a near-even split in benchmark wins, with the Intel part taking 7 victories and the AMD part taking 8, yet the nature of those wins reveals two distinct performance personalities. The Ultra 5 245T dominates in specific computational workloads like physics and prime number finding, while the Ryzen 7 9700X shows superior strength in broad multithreaded throughput and data-heavy tasks. Neither chip is a universal winner; your choice depends entirely on which workload profile matches your usage.

Head-to-Head Benchmarks

The most dramatic single result in the entire comparison belongs to the Intel Core Ultra 5 245T in Cinebench R23 single-core, where it scores 3699 against the Ryzen 7 9700X’s 2211. That is a 67.3% advantage, a massive gap for a single-threaded test. The Intel chip also wins Cinebench R23 multi-core with 26208 versus 20485, a 27.9% lead, which is surprising given that the AMD part has 16 threads versus Intel’s 14. The picture flips in Cinebench R15, where the AMD Ryzen 7 9700X scores 3178 versus Intel’s 2641, a 16.9% margin. This inconsistency between R15 and R23 suggests the Intel chip scales better in the newer Cinebench version’s workload.

In PassMark tests, the AMD Ryzen 7 9700X takes the lead in several key areas. Data compression is a clear AMD win at 437140 versus 283812, a 35.1% difference. Integer math also favors AMD at 120142 versus 88676, a 26.2% edge. The AMD part leads in multithread performance overall with 37161 versus 30833, a 17% margin, and in random string sorting at 46782 versus 34931, a 25.3% advantage. Extended instructions go to AMD as well, 35318 versus 22071, a 37.5% gap. The Ryzen 7 9700X also wins PassMark single-thread at 4654 versus 4367, though by a narrower 6.2%.

The Intel Core Ultra 5 245T counters with several notable wins beyond the Cinebench results. Find prime numbers is an Intel sweep at 324 versus 192, a 68.8% lead that mirrors the Cinebench R23 single-core dominance. Floating point math goes Intel’s way at 108499 versus 78999, a 37.3% advantage. Data encryption favors Intel at 23656 versus 21815, an 8.4% edge. Physics testing is close, with Intel at 2278 versus 2241, a 1.7% margin. The Intel chip also wins Cinebench R15 single-core at 372 versus 346, a 7.5% lead. Overall, Intel wins the high-score spikes in single-threaded and math-heavy tests, while AMD wins the broader throughput and data-management benchmarks.

Architecture Differences

The two processors come from completely different design philosophies. The Intel Core Ultra 5 245T uses Arrow Lake architecture on a 3nm process node from TSMC, with a die size of 243 mm² and 17,800 million transistors. It has 14 cores and 14 threads, meaning no hyperthreading, with a base clock of 2.20 GHz and boost clock of 5.10 GHz. Its cache layout includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. It uses the Intel Socket 1851 and is part of the Core Ultra Series 2, with integrated Arc Xe-LPG Graphics with 64 execution units.

The AMD Ryzen 7 9700X uses Zen 5 architecture on a 4nm process node from TSMC, with a much smaller die size of 70.6 mm² and 8,315 million transistors. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and boost clock of 5.50 GHz. Its cache includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. It uses the AMD Socket AM5 and is part of the 9000 series, with Radeon Graphics integrated. The AMD chip has a higher boost clock by 0.40 GHz, which helps explain its PassMark single-thread win despite the Intel chip’s Cinebench single-core dominance.

Memory support is identical in type—both use DDR5 in dual-channel mode—but bandwidth differs. The Intel chip has a memory bandwidth of 102.4 GB/s, while the AMD chip is rated at 89.6 GB/s. PCIe connectivity also differs: Intel provides Gen 5 with 20 lanes (CPU only), while AMD provides Gen 5 with 24 lanes (CPU only). Both support ECC memory. The AMD part has an unlocked multiplier, while the Intel part is locked. The Intel chip’s transistor count is more than double the AMD chip’s, reflecting its larger die and higher core count, but the AMD chip achieves competitive multithread scores with fewer cores and threads.

The Verdict

The data points to a clear split: the Intel Core Ultra 5 245T is the choice for single-threaded performance and math-intensive tasks, while the AMD Ryzen 7 9700X is the choice for broad multithreaded throughput and data manipulation. If your workload involves Cinebench rendering, floating point math, or prime number calculations, the Intel chip’s 27.9% lead in Cinebench R23 multi-core and 68.8% lead in prime number finding make it the stronger option. If your workload involves data compression, integer math, or general multitasking, the AMD chip’s 35.1% lead in compression and 26.2% lead in integer math are decisive. Both sit at the 86th percentile of all CPUs, and their average benchmark scores are nearly identical—38194 for Intel versus 37943 for AMD—so neither is a wrong choice. The Intel chip’s higher memory bandwidth and larger L3 cache may help in specific scenarios, but the AMD chip’s higher boost clock and unlocked multiplier offer flexibility. Choose Intel for peak single-core spikes and math workloads; choose AMD for balanced multithread performance and data-heavy tasks.

Where Each One Wins

The Intel Core Ultra 5 245T wins in Cinebench R23 multi-core and single-core, Cinebench R15 single-core, PassMark data encryption, find prime numbers, floating point math, and physics. This makes it the better option for rendering workloads that use newer Cinebench versions, scientific computing with heavy floating point operations, and any task involving prime number generation or encryption. Its 27.9% lead in Cinebench R23 multi-core is significant for content creation, and its 68.8% lead in prime number finding suggests strong integer math capabilities in certain algorithms.

The AMD Ryzen 7 9700X wins in Cinebench R15 multi-core, PassMark data compression, extended instructions, integer math, multithread, random string sorting, and single-thread. This makes it the better option for file compression and decompression, database operations involving string sorting, and general productivity suites that use integer math. Its 35.1% lead in data compression is substantial for archival tasks, and its 17% lead in multithread performance indicates better overall throughput for heavily threaded applications. The AMD chip’s PassMark single-thread win at 4654 versus 4367, a 6.2% margin, also gives it a slight edge in everyday responsiveness.
