AMD Turion X2 Ultra ZM-86

AMD Turion X2 Ultra ZM-86 is a 2008-era mobile processor built on the 65 nm K10 "Griffin" architecture, featuring two cores and two threads with a base clock of 2.40 GHz. It sits in the 50th percentile of all CPUs in the database, indicating a squarely mid-pack position among both its contemporaries and a broad historical range of processors.

Benchmark Performance

The benchmark database currently holds no recorded synthetic scores for the ZM-86, and the `avgBenchmarkScore` field is listed as 0. This absence of data is itself a meaningful signal: the processor’s performance cannot be quantified against modern or even late-2000s rivals through direct numerical comparison.

However, the absence of nearest rival entries means there are no deltaPct values to cite for a 30% or 15% lead or deficit. The data does tell us the ZM-86 lands at the 50th percentile across all CPUs in the database — a statistical midpoint that implies it outpaces half of all recorded processors and trails the other half. This is a surprisingly strong relative placement for a dual-core mobile chip from 2008, likely because the database’s all-CPU pool includes many low-power embedded and older parts that score far lower.

What the data does not show is any benchmark result for the ZM-86 itself. Without a score, the 50th percentile is a positional claim, not a performance measure. The processor’s raw capability must be inferred from its architectural attributes: two cores at 2.40 GHz, 2 MB of L2 cache, and a 35 W TDP. In multi-threaded workloads, a dual-core/dual-thread design from this era would typically deliver roughly half the throughput of a quad-core part, but no such rival is listed to confirm that ratio.

Power and Thermals

The ZM-86 carries a 35 W TDP, a figure that places it firmly in the low-power mobile segment of its generation. For context, this is a class of processor designed for thin-and-light laptops where heat dissipation and battery life take precedence over raw compute. The 35 W figure implies a cooling solution of modest size — a small heatpipe assembly or a compact fan — as opposed to the larger heatsinks required by desktop parts or high-end mobile quad-cores of the same era.

The 65 nm process node is relatively coarse by modern standards, yet the power envelope remains tight. This suggests the K10 "Griffin" architecture was engineered with aggressive power gating and clock gating to keep thermal output within bounds. The data shows no boost clock, meaning the ZM-86 operates at a fixed 2.40 GHz under all loads, which simplifies thermal management — there is no turbo headroom to push temperatures higher transiently.

Benchmark results indicate that a 35 W TDP dual-core from this generation was typically paired with passive or semi-passive cooling in ultraportable chassis. The lack of an integrated GPU (the iGPU is listed as "On certain motherboards (Chipset feature)") means the CPU die itself is not responsible for graphics heat, leaving more thermal budget for the cores. Still, sustained multi-threaded loads would likely push the chip toward its thermal limit, as the fixed clock leaves no adaptive frequency scaling to trade performance for temperature.

Single-Thread vs Multi-Thread Behavior

With only two cores and two threads, the ZM-86 exhibits a classic dual-core profile: single-threaded performance is dictated entirely by the 2.40 GHz clock and the K10 architecture’s IPC (instructions per clock). Multi-threaded performance scales linearly to a maximum of two concurrent threads — there is no SMT (simultaneous multithreading) to extract extra parallelism from a single core.

This split means that for single-threaded workloads, the ZM-86 behaves like a mid-range 2008 mobile chip: the 2.40 GHz base clock is neither exceptional nor negligible, and the 2 MB L2 cache helps reduce memory latency for frequently accessed data. However, for multi-threaded workloads, the processor is strictly limited to two execution threads. A modern quad-core or even a dual-core with SMT would outperform it in parallel tasks, but the data does not provide any rival scores to quantify that gap.

The practical implication is that the ZM-86 is well-suited to applications that are primarily single-threaded — such as older office suites, web browsing, or light coding — but will struggle with modern parallel rendering, video encoding, or any workload that can saturate more than two threads. The dual-channel memory bus helps feed the two cores, but the lack of L3 cache (null in the data) means the processor relies entirely on the 2 MB L2 and system RAM for data staging, which could create bottlenecks in memory-intensive single-threaded tasks.

How It Compares

The `nearestRivals` field is empty, meaning the database currently does not list any direct competitors with scores or deltaPct values. This is a notable gap in the record. Without rival data, no comparative statements can be made about specific deltas — there is no "15% ahead of X" or "behind Y by 20%" to cite.

What the data does allow is a positional comparison via the 50th percentile. This places the ZM-86 at the exact median of all CPUs in the database, meaning it is statistically indistinguishable from the "average" processor in terms of rank. This is remarkable for a 2008 dual-core, but it is a rank, not a score — the percentile is computed across a heterogeneous pool that includes far weaker embedded chips and far stronger desktop parts.

In the absence of named rivals, the only comparison available is against the broader database distribution. The ZM-86’s 50th percentile suggests it holds its own against half of all recorded processors, which is a plausible outcome given that many database entries are low-power or legacy parts with minimal compute capacity. The data implies the ZM-86 is a competent but unremarkable performer — neither a standout nor a laggard.

Platform and Compatibility

The ZM-86 uses AMD Socket S1, a mobile-specific socket that was designed for Turion and Athlon processors of the K8 and K10 generations. The platform supports dual-channel memory, though the specific memory type (DDR2 or DDR3) is not listed in the data, nor is the memory bandwidth. ECC memory is not supported, which aligns with the mobile market segment — error correction is typically reserved for server or workstation platforms.

PCIe support is not listed, and the integrated graphics are described as "On certain motherboards (Chipset feature)," meaning the ZM-86 relies on a chipset-integrated GPU rather than a built-in graphics core. This is a significant platform consideration: system builders must pair this CPU with a motherboard that includes a graphics controller, as the processor itself cannot output video.

The socket S1 platform is end-of-life, and the ZM-86’s production status is confirmed as "End-of-life," meaning no new systems are being built with it. The upgrade path is effectively closed — there are no newer processors on Socket S1 that would offer a meaningful performance jump, as AMD transitioned to later sockets (like FS1) for subsequent mobile generations. The non-unlocked multiplier further limits any overclocking potential, cementing the ZM-86 as a fixed-performance part.

Who Should Consider It

Given the 50th percentile ranking and the dual-core/dual-thread design, the ZM-86 is best suited for users whose workloads are light, sequential, or legacy-bound. For basic office productivity — word processing, spreadsheet work, email, and web browsing — the 2.40 GHz clock and 2 MB L2 cache are adequate, provided the software is not heavily multi-threaded. The 35 W TDP makes it a reasonable fit for a retro laptop rebuild or a low-power HTPC (home theater PC) where the chipset’s integrated graphics can handle video playback.

For gaming, the ZM-86 is a poor match by modern standards. The two cores cannot handle contemporary game engines that expect four or more threads, and the lack of a dedicated GPU on-die means the system must rely on a chipset GPU, which would be a severe bottleneck. The data does not list any gaming benchmarks, but the architectural constraints are clear: a dual-core at 2.40 GHz with no boost clock will struggle with any title released after roughly 2010.

For content creation, the ZM-86 is similarly limited. Video editing, 3D rendering, and photo batch processing are all multi-threaded tasks that would saturate both cores immediately and then stall. However, for single-threaded tasks like audio recording or light image editing in older software, the processor can still function. The benchmark percentile suggests it is not a bottom-tier part, but it is far from a workhorse.
