AMD FX-6300

The AMD FX-6300 is a desktop processor in the FX (Vishera) generation, manufactured by AMD on GlobalFoundries' 32 nm process with Piledriver architecture. It was released on 2012-10-22, carries the part number FD6300WMHKBOX, and had a launch MSRP of $132. The chip has six cores and six threads, a base clock of 3.50 GHz, a boost clock of 4.10 GHz, a 95 W TDP, and an unlocked multiplier.

Single-Thread vs Multi-Thread Behavior

The FX-6300 provides six cores and six threads, so the execution resource is fixed at six hardware contexts. Single-threaded code has a frequency ceiling represented by the 4.10 GHz boost clock, while sustained all-core operation is covered by the 3.50 GHz base clock. The cache hierarchy supports both access patterns: 288 KB of L1 cache, 6 MB of L2 cache, and 8 MB of shared L3 cache. A lightly threaded workload can rely on the shared L3 to keep data close to a single core, while a six-thread workload can occupy all cores at once. The 8 MB shared L3 is particularly relevant to parallel workloads because it gives all six threads a common pooled cache, while the 6 MB L2 serves the core-local caching side.

For real workloads, the practical split is between tasks that scale to all six threads and tasks that cannot use more than one or two cores. The 4.10 GHz boost clock is the high point for latency-sensitive single-thread work, but the issue is that the database does not record per-workload benchmark scores, so the actual measured balance between single-thread and multi-thread performance cannot be stated. The architecture, cache sizes, and clock range define the envelope, but not the measured split. A workload that can spread across six threads has six cores to work with; a workload that depends on one core has a 3.50 GHz base floor and a 4.10 GHz boost ceiling. The database entry does not say whether the boost clock applies to one core or to multiple cores under load, so a precise multi-thread frequency analysis is not possible from the data alone.

Power and Thermals

The FX-6300's TDP is 95 W. That is the only thermal rating in the entry, and it is the figure that any cooling solution must be able to dissipate. The die is 315 mm² and contains 1,200 million transistors on the 32 nm GlobalFoundries process, which provides some context for the thermal density. A 95 W TDP places the part in a mainstream desktop thermal class, though the database does not list a bundled cooler, heatsink specification, or recommended thermal design. The unlocked multiplier means overclocking is possible, which would move power consumption beyond the stock 95 W rating if the user raises voltage or frequency, but the database does not quantify that headroom.

Because the production status is end-of-life, there is no current cooling guidance in the database. The measured data shows only the 95 W TDP, the 32 nm process, the 315 mm² die, and the 1,200-million-transistor count as the thermal context. A cooler designed for a 95 W-class desktop processor is the implied tier, but the database does not verify specific cooler compatibility. In the absence of thermal test results, the 95 W TDP is the boundary that separates this part from lower-power chips and from higher-end FX parts that would require more robust cooling. The thermal behavior under sustained multi-thread load would depend on the motherboard power delivery and chassis airflow, neither of which is specified in the entry.

Platform and Compatibility

The FX-6300 fits AMD Socket AM3+. Memory support is DDR3 through a dual-channel interface with 29.9 GB/s of aggregate memory bandwidth. ECC memory is not supported, so the platform is aimed at standard desktop memory rather than validated error-correcting configurations. The PCIe interface is Gen 2, which is the generation of the platform's expansion and graphics connectivity; the database does not specify lane counts. Integrated graphics are not part of the CPU itself: the entry lists integrated graphics as a chipset feature on certain motherboards, meaning display output depends on the motherboard chipset rather than on a GPU block inside the processor.

The multiplier is unlocked, which allows overclocking through frequency multiplier adjustment. The boxed part number is FD6300WMHKBOX. The market segment is desktop, and the production status is end-of-life. The release date is 2012-10-22, which places the platform in that era of AMD socket and DDR3 systems. From an upgrade-path perspective, the socket AM3+ connector is the fixed physical boundary, and the end-of-life status means there is no ongoing product maintenance in the database. The database lists no drop-in successor CPUs or alternative upgrade parts for this platform, so any upgrade decision would have to be based on the existing AM3+ socket and DDR3 memory support. The absence of ECC support and the presence of PCIe Gen 2 define the platform's memory and I/O capabilities, while the chipset-based integrated graphics option means users need a discrete GPU unless the motherboard provides display output through its chipset.

How It Compares

The nearest-rival data in the database is empty. There are no named competitor entries, no rival benchmark scores, and no rival-specific delta percentages to report for the AMD FX-6300. The only comparison point supplied is the global percentile field, which lists the processor at the 50th percentile of all CPUs in the database. That is a median position: half of the database population is ranked above it and half below it. Without a nearest-rival list, the specific distance to any neighboring CPU cannot be quantified, and no direct competitor comparison is available in this entry.

Benchmark Performance

The benchmark array for the FX-6300 is empty, and no average benchmark score is provided. As a result, absolute workload scores cannot be quoted, and exact percentage deltas against other CPUs cannot be computed from this data. The sole quantitative performance indicator is the 50th percentile among all CPUs in the database. This percentile places the processor in the middle of the database distribution, meaning it is not near the top of the field but also not in the lower tail.

From a benchmark engineering perspective, the lack of measured scores forces the performance analysis to remain architectural. The processor has six cores and six threads, a 3.50 GHz base clock, a 4.10 GHz boost clock, 288 KB of L1 cache, 6 MB of L2 cache, 8 MB of shared L3 cache, and 29.9 GB/s of dual-channel DDR3 bandwidth. Those figures define the performance envelope, but they do not produce the exact percentage advantage or disadvantage that a benchmark-delta table would normally provide. Because the nearest-rival list is also empty, no claim such as "the FX-6300 is a specific percentage faster than a named rival" is supported by the data. The 50th percentile rank is the only measured position in the entry, and even that rank cannot be decomposed into single-thread and multi-thread components without workload-level records.
