AMD Phenom II X4 830

The AMD Phenom II X4 830 is a desktop processor built on the K10 architecture (Deneb) for Socket AM3, released in late August 2009. With four cores and four threads running at a fixed 2.80 GHz, it targets entry-level computing. Its average benchmark score of 606 places it in the 14th percentile of all CPUs in the database, meaning it outperforms only 14% of the processor population. The chip is end-of-life, and its performance profile aligns closely with several low-end Intel mobile and embedded parts, as the nearest rival list shows near-identical scores.

Benchmark Performance

The Phenom II X4 830 delivers a Cinebench R23 multi-core score of 1761 and a single-core score of 248. In Cinebench R20, the multi-core result is 739, while single-core is 104. The older Cinebench R15 multi-core test yields 177. These numbers are modest by any modern standard. The average benchmark score of 606 exactly matches that of the Intel Core i5-2430M, and it sits within 0.1% of the Intel Atom x7-E3950, Intel Core i7-610E, and Intel Celeron 4305UE. The deltaPct values for all four nearest rivals are 0.0% or 0.1%, indicating statistical parity. In other words, the Phenom II X4 830 performs at the same level as these four very different chips—a mobile Core i5, a low-power Atom, a 2010 embedded Core i7, and a modern Celeron. The 14th percentile ranking reinforces its position at the low end of the performance spectrum. For comparison, a modern mid-range desktop CPU would typically sit in the 60th to 80th percentile, but no such rival is listed here. The data shows that this processor is suitable only for light, legacy workloads.

Single-Thread vs Multi-Thread Behavior

The single-core scores are exceptionally low: 104 in Cinebench R20 and 248 in Cinebench R23. These numbers reflect a per-core capability that is roughly a fifth to a tenth of contemporary high-end chips, though no direct rival single-core figures are provided. The multi-core scores, while still low, show a better scaling pattern. The Cinebench R23 multi-core score of 1761 is 7.1 times the single-core score of 248. Since the processor has exactly four cores and four threads, this scaling is higher than the theoretical 4x limit, which suggests that the single-core score is disproportionately weak relative to the multi-core result. This can happen when the test workload is memory-bound or when the single-core test is more sensitive to clock speed and IPC—both of which are limited on this 45nm Deneb design. In real-world terms, the multi-thread advantage will be noticeable in applications that can use all four cores, such as video encoding or batch photo processing, but the absolute throughput remains low. Conversely, lightly threaded tasks like web browsing, office document editing, or legacy software will feel sluggish because of the weak single-thread performance. The split indicates that the CPU is better suited to parallelizable workloads than to interactive, latency-sensitive tasks.

Power and Thermals

The Phenom II X4 830 carries a TDP of 95 watts. This is a relatively high thermal design power for a processor with such modest performance. The 45nm manufacturing process (GlobalFoundries, 758 million transistors on a 258 mm² die) contributes to this power draw. A 95W TDP implies that a capable air cooler is necessary—a low-profile or stock-style cooler may struggle under sustained load, but a standard tower cooler will suffice. The chip does not have a boost clock, so the power draw remains constant under load; there is no turbo headroom to manage. Because the processor is end-of-life and was designed in the late 2000s, its power efficiency is poor compared to modern parts. However, for a system that already has an AM3 motherboard and a suitable cooler, the thermal requirements are not exotic. The absence of an unlocked multiplier means overclocking is not possible, so the 95W TDP is the fixed operating point.

Platform and Compatibility

The Phenom II X4 830 uses the AMD Socket AM3, which supports DDR3 memory in a dual-channel configuration with a peak bandwidth of 21.3 GB/s. ECC memory is supported, making it suitable for basic server or workstation builds where data integrity is critical. The processor does not include integrated graphics; any display output must come from a discrete graphics card or a motherboard chipset with integrated graphics. The PCIe interface is Gen 2, which limits modern GPU bandwidth but is sufficient for older graphics cards. The platform is legacy: the socket is AM3, and the processor is end-of-life, so there is no upgrade path to newer CPUs without changing the motherboard and memory. The part number HDX830WFK4DGM indicates the specific SKU, but the key takeaway is that this is a closed platform. For users with existing AM3 boards, the Phenom II X4 830 can serve as a drop-in replacement for older dual-core or low-end quad-core chips, but the platform itself offers no future expansion.

How It Compares

vs. Intel Core i5-2430M

The Phenom II X4 830 and the Intel Core i5-2430M share an identical average benchmark score of 606, with a deltaPct of 0%. The Core i5-2430M is a mobile processor from 2011, while the Phenom is a desktop part from 2009. Despite the different form factors and release years, the two deliver the same level of overall performance. In practice, the Phenom's four desktop cores may handle multi-threaded tasks slightly better due to higher sustained power limits, but the i5-2430M's newer architecture gives it an edge in single-thread efficiency. The data shows parity, so users should base their choice on platform availability rather than performance.

vs. Intel Atom x7-E3950

The Atom x7-E3950 is a low-power embedded chip with a 606 average score, just 0.1% higher than the Phenom. This is a remarkable result: a 2016-era Atom with far lower power consumption matches a 2009 desktop quad-core. The Atom's advantage lies in its modern instruction set and power efficiency, while the Phenom's advantage is its higher memory bandwidth (21.3 GB/s) and support for ECC. For embedded or fanless systems, the Atom is clearly superior, but the Phenom can still serve in legacy desktop roles where its 95W TDP is not a concern.

vs. Intel Core i7-610E

The Core i7-610E, a 2010 embedded processor, also scores 606 with a 0.1% delta. This comparison highlights how the Phenom II X4 830 sits in a performance tier that spans both mobile and embedded segments. The i7-610E is a dual-core with Hyper-Threading, while the Phenom is a true quad-core. The similar scores suggest that the Phenom's extra physical cores do not overcome the i7's higher IPC and clock speeds. For industrial or embedded applications, the i7-610E is the more modern choice, but the Phenom's AM3 platform may be easier to source for hobbyist builds.

vs. Intel Celeron 4305UE

The Celeron 4305UE, a 2019 embedded chip, scores 605—just 0.1% lower than the Phenom. This is the only rival that the Phenom edges out, albeit by a negligible margin. The Celeron is a dual-core with a much lower TDP and integrated graphics, but its single-thread performance is likely higher. The Phenom's quad-core design gives it an advantage in multi-threaded workloads, but the Celeron's modern architecture and lower power draw make it the better choice for new designs. The deltaPct of 0.1% is within measurement error, so the two are effectively tied.

Who Should Consider It

The Phenom II X4 830 is a processor for legacy systems and undemanding workloads. Its Cinebench R23 multi-core score of 1761 is too low for modern video editing, 3D rendering, or heavy compilation. The single-core score of 248 makes it unsuitable for fast, responsive desktop use in current operating systems; web pages with heavy JavaScript or office suites with complex documents will feel sluggish. However, for basic office tasks such as word processing, spreadsheet work, and email, the CPU can still function if paired with adequate RAM and an SSD. It can also handle legacy software from the Windows XP/Vista era without issue. The support for ECC memory makes it viable for a low-traffic home server or a NAS, where multi-threaded file transfers and light virtualization are the primary workloads. Gamers should avoid this chip; even older titles from the mid-2010s will be bottlenecked by the low single-thread performance. In short, the Phenom II X4 830 is only worth considering if you already own an AM3 motherboard and want to revive an old system for light productivity or as a secondary machine. It is not a purchase recommendation for any new build.
