AMD Ryzen AI 7 450 vs Intel Xeon 6507P Comparison

Head-to-Head Benchmarks

The benchmark data reveals a clear split between these two processors. The Intel Xeon 6507P dominates the head-to-head comparison, winning 12 of the 15 recorded tests. The AMD Ryzen AI 7 450 takes only 3 wins, two of which are the same PassMark single-thread test recorded under slightly different names.

The largest margin belongs to the Intel part in PassMark's find prime numbers test, where it scores 224 against AMD's 89, a 151.7% advantage. This is an extreme outlier, but it signals a consistent pattern of Intel's architecture being far stronger in integer-heavy, compute-intensive workloads. The Xeon also wins Cinebench R23 single-core by 83.9%, scoring 3747 versus 2038, and Cinebench R15 single-core by 75.3%, scoring 377 versus 215. These are enormous gaps for single-threaded tests, which typically favor higher boost clocks. The Intel part boosts to 4.30 GHz, while the AMD part boosts to 5.10 GHz, yet the Intel chip still wins decisively in these older Cinebench versions.

In Cinebench R23 multi-core, the Xeon 6507P scores 26548, which is 44.9% ahead of the Ryzen AI 7 450's 18316. PassMark physics shows an 86% lead for Intel (2935 versus 1578), and floating-point math is 27.8% ahead (69604 versus 54447). Extended instructions go to Intel by 22.3% (27385 versus 22400). PassMark multi-thread favors Intel by 18.5% (31233 versus 26350). Data compression is 12.8% better on the Xeon (356190 versus 315906), data encryption is 9.3% better (17753 versus 16247), and random string sorting is 11.3% better (39682 versus 35648). Integer math is nearly a tie: Intel scores 88877 versus AMD's 88531, a 0.4% edge.

The AMD Ryzen AI 7 450's only meaningful wins are in PassMark single-thread, where it scores 3901 against Intel's 3643, a 6.6% advantage. It also wins Cinebench R15 multi-core narrowly, 2713 versus 2676, a 1.4% edge. These results suggest that in the newest single-thread test, AMD's higher boost clock does translate into a win, but it is a modest one compared to the magnitude of Intel's victories in most other categories.

Looking at the broader database context, the Xeon 6507P sits at the 87th percentile among all CPUs, with an average benchmark score of 40426. Its nearest rivals include the AMD Ryzen 9 7940H (delta 0%), Intel Core Ultra X7 368H (delta -0.2%), Intel Xeon 6369P (delta 0.2%), and Intel Core i9-13905H (delta 0.3%). The Ryzen AI 7 450 also sits at the 87th percentile, with an average score of 39485. Its nearest rivals are the AMD Ryzen 7 PRO 8840HS (delta -0.3%), AMD Ryzen 7 PRO 8845HS (delta 0.4%), AMD EPYC 4245P (delta 0.7%), and AMD Ryzen 7 9800X3D (delta -0.7%). Both processors occupy a similar performance tier in the aggregate, despite the Xeon's large wins in individual tests.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Xeon 6507P uses the Granite Rapids architecture, built on Intel's 5 nm process node, and belongs to the Xeon 6 (Granite Rapids-SP) generation. It is a server and workstation part, designed for sustained heavy loads. The AMD Ryzen AI 7 450 uses the Zen 5 architecture, built on TSMC's 4 nm process node, and belongs to the Ryzen AI 400 (Zen 5 / Zen 5c) generation. It is a mobile part, engineered for power efficiency within a laptop thermal envelope.

Both have 8 cores and 16 threads, so the core count is identical. The difference lies in how those cores are fed and cooled. The Xeon has a base clock of 3.50 GHz and a boost clock of 4.30 GHz, while the AMD part has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The AMD chip boosts much higher, but its base clock is far lower. The thermal design power differs dramatically: the Xeon is rated at 150 watts, while the Ryzen AI 7 450 is rated at 28 watts. This explains the performance split in sustained multi-threaded workloads, where the Xeon can draw far more power and maintain higher performance over time.

Cache hierarchies also differ. The Xeon provides 112 KB of L1 per core, 2 MB of L2 per core, and 48 MB of shared L3 cache. The AMD part provides 80 KB of L1 per core, 1 MB of L2 per core, and only 8 MB of L3 cache. The Xeon's L3 cache is six times larger, which helps in workloads with large working sets. The AMD chip has a die size of 195 mm², while the Xeon's die size is not recorded in the database.

Memory support diverges sharply. The Xeon supports DDR5 with an eight-channel memory bus and a theoretical bandwidth of 409.6 GB/s. The AMD part supports both DDR5 and LPDDR5X, but with a dual-channel bus and a bandwidth of 89.6 GB/s. The Xeon's memory bandwidth is roughly 4.5 times higher, which is critical for server workloads that stream large datasets. Both support ECC memory, which is notable for a mobile chip.

PCIe connectivity also differs. The Xeon offers Gen 5 with 88 lanes (CPU only), while the AMD part offers Gen 4 with 16 lanes (CPU only). The Xeon is clearly designed to drive many expansion cards, NVMe drives, and accelerators. The AMD part has integrated graphics in the form of a Radeon 860M, while the Xeon has no integrated graphics, requiring a discrete GPU or a server BMC for display output.

Where Each One Wins

The Intel Xeon 6507P is the clear winner for compute-heavy, multi-threaded server and workstation workloads. Its 44.9% lead in Cinebench R23 multi-core and 86% lead in PassMark physics show that it can handle CPU-bound rendering, simulation, and physics calculations far better than the AMD chip. The 151.7% lead in find prime numbers suggests an enormous advantage in integer-heavy algorithms, which appear in cryptography, hashing, and scientific computing. The 27.8% lead in floating-point math points to strength in numerical analysis and engineering simulation. Data compression and encryption also favor the Xeon, with 12.8% and 9.3% leads respectively, making it suitable for database workloads and file servers that perform real-time compression or encryption.

The Xeon's eight-channel memory bus and 409.6 GB/s of bandwidth make it the obvious choice for memory-bound workloads. A server running large in-memory databases, virtualization hosts with many VMs, or data analytics jobs that stream through massive arrays will benefit from the memory subsystem. The 88 PCIe Gen 5 lanes allow it to connect to many high-speed devices simultaneously, which is essential for storage arrays or GPU clusters. The 48 MB of L3 cache helps with workloads that repeatedly access a moderately sized working set.

The AMD Ryzen AI 7 450 wins in the PassMark single-thread test, scoring 3901 versus 3643, a 6.6% advantage. This means for lightly threaded applications that rely on a single core, such as some legacy software, spreadsheet macros, or certain scripting workloads, the AMD part will feel snappier. Its 5.10 GHz boost clock is the highest of the two, and in short bursts it can outperform the Xeon in single-core scenarios. The AMD chip also wins Cinebench R15 multi-core by a small margin, 2713 versus 2676, a 1.4% edge, which suggests that in very short multi-threaded bursts, the mobile chip can briefly outpace the server chip before thermal or power limits kick in.

The Ryzen AI 7 450 is the only one of the two with integrated graphics, the Radeon 860M. This makes it suitable for a laptop or compact mobile workstation where a discrete GPU is not always available. It also supports LPDDR5X memory in addition to DDR5, which allows for lower power memory subsystems in thin-and-light designs. The 28-watt TDP means it can be cooled by a modest laptop cooler, whereas the 150-watt Xeon requires a substantial server heatsink and airflow.

For use cases that involve long-duration, heavy multi-threading, the Xeon wins decisively. For short single-threaded bursts and mobile deployments with integrated graphics, the AMD part has a role. The choice hinges on whether the workload is sustained and memory-heavy (Xeon) or bursty and power-constrained (AMD).
