AMD Ryzen 5 2600 vs Intel Core Ultra 7 256V Comparison

The AMD Ryzen 5 2600 and Intel Core Ultra 7 256V represent two very different eras of processor design, and their benchmark results reflect that divide clearly. The Intel part wins 13 of the 15 head-to-head tests, often by substantial margins, while the AMD chip manages only two narrow victories. The data shows a processor that trades blows on specific workloads but ultimately favors the newer Intel architecture in overall performance.

Head-to-Head Benchmarks

The Intel Core Ultra 7 256V dominates the multi-core and single-core synthetic tests. In Cinebench R15 multi-core, the Intel part scores 1583.5 against the Ryzen 5 2600’s 1248, a 21.2% advantage. The gap widens dramatically in single-core tests: Intel’s 285.5 in Cinebench R15 single-core beats AMD’s 157.3 by 44.9%. Geekbench shows a similar story, with Intel leading multi-core 8643 to 5648 (34.7% faster) and single-core 1990 to 1154 (42% faster). These are not marginal wins — the Ultra 7 256V is in a different performance class for general compute.

The PassMark suite reinforces this trend. Intel wins floating-point math by a massive 60.8% (58576 vs 22942) and extended instructions by 54.2% (15643 vs 7168). The physics test shows Intel at 1595 versus AMD’s 673, a 57.8% lead. Even in integer math, where AMD’s 44518 narrowly beats Intel’s 43358, the 2.7% margin is far smaller than Intel’s typical advantage. The single-thread PassMark score tells the same story as Cinebench: Intel’s 4029 is 44.4% higher than AMD’s 2239.

The AMD Ryzen 5 2600’s two wins are noteworthy but narrow. It takes data compression with 187062 versus 184985, a 1.1% edge. It also wins integer math by 2.7%. These are the only tests where the older chip comes out ahead, and both margins are small enough to be considered statistical noise rather than a meaningful performance advantage. The Intel part wins the remaining 13 tests, including data encryption (13998 vs 12429, an 11.2% lead) and random string sorting (22481 vs 21591, a 4% lead).

Where Each One Wins

The Ryzen 5 2600’s strengths are narrowly focused on specific integer-heavy and compression workloads. In data compression, it edges ahead by just over one percent, suggesting that its older Zen architecture handles certain repetitive data operations efficiently. The integer math win, albeit by 2.7%, indicates that for pure integer arithmetic, the six-core, twelve-thread design can still hold its own against the newer Intel part.

The Intel Core Ultra 7 256V wins everywhere else, and often by margins that define its character. It is particularly strong in single-threaded and floating-point workloads, where its 44-61% leads show a generational leap in per-core efficiency. The physics test, which often benefits from both strong single-thread performance and efficient scheduling, shows a 57.8% advantage. For users running modern applications that scale with single-core speed — web browsing, office productivity, and most games — the Ultra 7 256V is clearly the better choice.

Multi-core throughput is also firmly in Intel’s court. The 32.6% lead in PassMark multithread and the 21.2% lead in Cinebench R15 multi-core show that even with fewer threads (8 vs 12), the Intel part’s higher clock speeds and architectural efficiency win out. The average benchmark score reflects this overall superiority: Intel’s 21112 vs AMD’s 21484 is close, but the head-to-head results show Intel winning the tests that matter most for modern workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 2600 uses the Zen architecture on a 12 nm process from GlobalFoundries, codenamed Pinnacle Ridge. This is a 6-core, 12-thread design with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. Its cache layout includes 96 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The chip is built on a 213 mm² die with 4,800 million transistors.

The Intel Core Ultra 7 256V uses the Lunar Lake architecture on a 3 nm process from TSMC. This is an 8-core, 8-thread design with a base clock of 2.20 GHz but a much higher boost clock of 4.80 GHz. Its cache is configured differently: 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel does not report transistor count or die size, but the 3 nm node represents a significant process advantage over AMD’s 12 nm.

The clock speed difference is telling. Intel’s boost clock of 4.80 GHz is 23% higher than AMD’s 3.90 GHz, which largely explains the single-thread performance gap. The power envelope is also starkly different: Intel has a 17W TDP versus AMD’s 65W TDP. This makes the Intel part far more efficient per watt, though the AMD chip’s higher TDP allows for more sustained multi-core performance in a desktop context.

Memory and PCIe support differ significantly. AMD uses DDR4 with dual-channel memory and 46.9 GB/s bandwidth, while Intel’s memory support is listed as “unknown, depends on motherboard” but also uses dual-channel. For PCIe, AMD offers Gen 3 with 16 CPU lanes, while Intel provides Gen 5 with 4 CPU lanes. This makes AMD better suited for multi-GPU setups, while Intel’s Gen 5 lanes offer higher bandwidth per lane for newer storage devices.

Specification Differences

The core and thread counts differ: AMD has 6 cores and 12 threads, while Intel has 8 cores and 8 threads. This means AMD relies on simultaneous multithreading to increase throughput, whereas Intel uses more physical cores but no SMT. The base clocks are 3.40 GHz for AMD and 2.20 GHz for Intel, but the boost clocks are 3.90 GHz and 4.80 GHz, respectively.

The process node is a major differentiator: 12 nm for AMD versus 3 nm for Intel. AMD’s TDP is 65W, while Intel’s is 17W — a fourfold difference in power draw. Sockets are incompatible: AMD Socket AM4 for the Ryzen 5 2600, and Intel BGA 2833 for the Ultra 7 256V. The AMD chip is a desktop part with an unlocked multiplier, while the Intel chip is a mobile part with a locked multiplier.

Integrated graphics are present only on the Intel part, with Arc 140V. AMD does not list integrated graphics. Market segments reflect this: AMD is Desktop, Intel is Mobile. The release dates are far apart — AMD launched on 2018-04-18, Intel on 2024-09-23. AMD’s launch MSRP is $199; Intel has no listed MSRP. Cache sizes also differ, with AMD having 16 MB L3 shared and Intel having 12 MB L3 shared, though Intel has larger per-core L1 and L2 caches.
