Head-to-Head Benchmarks

The recorded benchmark data shows a decisive overall advantage for the Intel Core 5 213PTE, which wins 14 of the 17 head-to-head comparisons. The Intel Core Ultra 7 266V wins only 3. The most striking margin appears in integer math, where the Core 5 213PTE scores 93,109 against 41,558 for the Ultra 7 266V, a 124% advantage. That is the largest performance gap between the two processors across every test in the database.

The Cinebench suite tells a consistent story. In all six Cinebench tests, the Core 5 213PTE leads with a 31.5% advantage. Multicore results are 2,192 versus 1,667 in Cinebench R15, 9,135 versus 6,948 in Cinebench R20, and 21,751 versus 16,544 in Cinebench R23. Single-core results follow the same pattern: 309 versus 235 in R15, 1,289 versus 980 in R20, and 3,070 versus 2,335 in R23. The uniformity of the 31.5% delta across all six tests indicates a consistent per-thread advantage, not merely a core-count effect.

PassMark results add further detail. Data compression favors the Core 5 213PTE at 261,083 versus 187,050, a 39.6% lead. Floating point math shows a 26% advantage at 71,722 versus 56,923.

Multithreaded performance overall lands at 25,590 versus 19,461, another 31.5% gap.

The race is narrow in two areas. Data encryption shows only a 4.3% lead for the Core 5 213PTE at 14,413 versus 13,822. Extended instruction workloads are nearly tied at 16,146 versus 15,928, a 1.4% difference. These close results suggest the two chips have comparable throughput on specific optimized instruction paths.

The Ultra 7 266V does claim victories. Prime number finding favors it at 191 versus 157, a 17.8% lead. Single-thread PassMark results show 3,943 versus 3,718, a 5.7% advantage. The single-thread and singlethread entries are identical tests with identical scores, so the 3,943 result appears twice in the database. Prime number search is often sensitive to memory latency and branch handling, while the PassMark single-thread test reflects a mix of desktop workloads where the Ultra 7 has a measurable edge.

The overall average benchmark score confirms the hierarchy. The Core 5 213PTE averages 32,924, placing it in the 83rd percentile of all CPUs. The Ultra 7 266V averages 23,297, placing it in the 76th percentile. The nearest recorded rivals for the Core 5 213PTE are the Intel Core i7-12700 at 32,942 (0.1% higher), the AMD Ryzen 7 PRO 6850H at 32,812 (0.3% lower), the AMD Ryzen 7 7800X3D at 33,079 (0.5% higher), and the AMD Ryzen 7 8700G at 33,089 (0.5% higher). The Ultra 7 266V lands next to the AMD Ryzen 7 5800H at 23,277 (0.1% higher), the Intel Core i9-11900F at 23,254 (0.2% higher), the Intel Core Ultra 9 288V at 23,219 (0.3% higher), and the AMD EPYC 4124P at 23,167 (0.6% higher). The Core 5 213PTE therefore competes with desktop mid-range parts from the prior generation, while the Ultra 7 266V sits at the level of older high-end mobile and entry server chips.

Architecture Differences

The two processors share a manufacturer but diverge sharply in design. The Intel Core 5 213PTE is a desktop part built on the Bartlett Lake platform, manufactured on a 10 nm process at Intel. The Intel Core Ultra 7 266V belongs to the Core Ultra Series 2, uses the Lunar Lake architecture, and is fabricated on a 3 nm process at TSMC. The process node gap is substantial: 10 nm versus 3 nm.

Both chips have 8 cores, but thread counts differ. The Core 5 213PTE supports 16 threads, indicating simultaneous multithreading. The Ultra 7 266V supports 8 threads, one per core. This explains much of the multicore benchmark gap, though single-core Cinebench results also favor the Core 5 213PTE by the same 31.5%, so the desktop chip has a per-core edge in that workload regardless of threading.

Cache layouts are distinctly different. The Core 5 213PTE uses 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Ultra 7 266V uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. The Ultra 7 has more per-core cache in the first two levels, but less than half the total L3. The larger L3 on the Core 5 213PTE likely assists in data-heavy workloads such as compression and random string sorting, where the desktop chip leads by roughly 31% to 40%.

Clock behavior also separates them. The Core 5 213PTE has a 2.10 GHz base clock and a 5.20 GHz boost clock. The Ultra 7 266V has a 2.20 GHz base and a 5.00 GHz boost. The Ultra 7 starts slightly higher but boosts lower. The recorded single-thread PassMark result, however, favors the Ultra 7, so raw clock alone does not predict the outcome.

Thermal design power differs by a wide margin. The Core 5 213PTE is rated at 45 W, while the Ultra 7 266V is rated at 17 W. The Ultra 7 is built for mobile use and draws far less power, which shows in its lower benchmark scores but also indicates a different performance-per-watt profile. The Core 5 213PTE targets desktop Socket 1700, while the Ultra 7 266V uses Intel BGA 2833, a soldered mobile package.

Integrated graphics diverge completely. The Core 5 213PTE carries UHD Graphics 730, a modest desktop iGPU. The Ultra 7 266V carries Arc 140V, a much more capable graphics solution typical of a premium mobile chip. The database contains no graphics benchmarks for either part, so the comparison here is limited to specification differences.

Memory support also differs. The Core 5 213PTE supports both DDR4 and DDR5 in dual-channel mode with 76.8 GB/s of bandwidth. The Ultra 7 266V supports LPDDR5X, with bandwidth dependent on the motherboard, at 136.5 GB/s. The Ultra 7 has nearly double the memory bandwidth ceiling, which may contribute to its strong prime number and single-thread PassMark results. The Core 5 213PTE supports ECC memory; the Ultra 7 does not.

PCIe connectivity is another split. The Core 5 213PTE provides Gen 5 with 16 lanes from the CPU. The Ultra 7 266V provides Gen 5 with only 4 lanes from the CPU. The desktop chip clearly offers far more expansion capability, while the mobile chip is constrained by its package and platform.

Release timing is not equal. The Ultra 7 266V was released in September 2024. The Core 5 213PTE was released in March 2026. The desktop part is newer by roughly a year and a half, yet it uses older fabrication technology. The production status for both is listed as active.

The Core 5 213PTE has a launch MSRP of $221. The Ultra 7 266V has no recorded launch MSRP in the database.

Where Each One Wins

The Intel Core 5 213PTE wins across the majority of compute-oriented workloads. Every Cinebench result, both single-core and multicore, goes to the desktop chip with a 31.5% margin. PassMark multithread, floating point math, data compression, physics, random string sorting, data encryption, and extended instructions all favor the Core 5 213PTE. The integer math result is the most lopsided at 124%, indicating a massive advantage in workloads dominated by integer operations. The 16-thread configuration and larger L3 cache make this the better choice for rendering, compilation, simulation, and other parallel compute tasks. The 16 Gen 5 PCIe lanes also make it the stronger platform for desktop expansion.

The Intel Core Ultra 7 266V wins in prime number finding and in the PassMark single-thread test. The prime number result suggests a latency-sensitive advantage, likely tied to its 192 KB L1 per core and 2.5 MB L2 per core, which are both larger than the Core 5 213PTE's per-core caches. The single-thread PassMark score of 3,943 versus 3,718 indicates that for lightly threaded desktop responsiveness, the Ultra 7 has a slight edge. Its 136.5 GB/s memory bandwidth is also significantly higher, which can benefit integrated GPU workloads and memory-bound tasks. The 17 W TDP makes it suitable for thin-and-light mobile systems where sustained multicore performance is secondary to power efficiency. The Arc 140V iGPU is a far more capable integrated graphics solution than UHD Graphics 730, though the database records no graphics benchmarks to quantify this.

The Verdict

The benchmark data clearly separates these two processors by intended role. The Intel Core 5 213PTE is a desktop processor built for throughput. It wins 14 of 17 comparisons, leads by 124% in integer math, and holds a uniform 31.5% advantage across the entire Cinebench suite. Its 16 threads, 24 MB L3 cache, 5.20 GHz boost clock, and 16 Gen 5 PCIe lanes position it for desktop systems where CPU compute and platform expandability matter most. Its 83rd percentile standing among all CPUs and its placement alongside parts like the Intel Core i7-12700 and AMD Ryzen 7 7800X3D confirm that it competes in the upper mid-range desktop tier.

The Intel Core Ultra 7 266V is a mobile processor designed for efficiency and single-thread responsiveness. It draws only 17 W, uses a 3 nm process, and delivers a 136.5 GB/s memory bandwidth that exceeds the desktop chip's 76.8 GB/s. Its wins in prime number finding and the PassMark single-thread test indicate strengths in latency-sensitive and lightly threaded work. The 76th percentile standing and proximity to the AMD Ryzen 7 5800H and Intel Core i9-11900F place it at a lower absolute performance level, but its Arc 140V graphics and LPDDR5X support make it suited to compact mobile platforms.

The choice depends entirely on the platform and workload profile. For pure CPU compute, parallel workloads, and desktop expansion, the Core 5 213PTE is the stronger part by every recorded multicore measurement. For mobile systems, power-constrained operation, and workloads that favor single-thread latency, the Ultra 7 266V offers specific advantages that the desktop chip cannot match. The data does not support a single winner across all scenarios. It supports a clear split: the Core 5 213PTE for desktop compute, the Ultra 7 266V for mobile efficiency.
