AMD A10-7870K vs AMD A8-9600 Comparison

FAQ

Q: Which processor has the higher clock speed?

A: The AMD A10-7870K runs at a base clock of 3.90 GHz and boosts to 4.10 GHz, while the AMD A8-9600 operates at a base of 3.10 GHz and boosts to 3.40 GHz. The A10-7870K holds a clear frequency advantage across all operating states.

Q: Do these CPUs use the same memory standard?

A: No. The A10-7870K supports DDR3 memory with dual-channel configuration and 34.1 GB/s bandwidth, while the A8-9600 uses DDR4 memory with dual-channel configuration and 38.4 GB/s bandwidth. The A8-9600 has higher theoretical memory bandwidth despite running on the newer standard.

Q: Are both processors unlocked for overclocking?

A: The A10-7870K has its multiplier unlocked, allowing manual overclocking. The A8-9600 has a locked multiplier, which prevents direct clock adjustment. This is a significant distinction for enthusiasts.

Q: What is the transistor count difference between the two?

A: The A10-7870K integrates 2,411 million transistors on a 245 mm² die, while the A8-9600 packs 3,100 million transistors on a 250 mm² die. The A8-9600 has roughly 29% more transistors despite similar die area.

Q: Which CPU has better single-core performance?

A: According to Cinebench R23 single-core results, the A10-7870K scores 420 points versus 394 points for the A8-9600, a 6.6% advantage for the older part. The A10-7870K also leads in Cinebench R20 single-core by 6.7%.

Q: Are both processors still in production?

A: No. The A10-7870K is marked as End-of-life, while the A8-9600 has Active production status. This affects availability and platform longevity.

The Verdict

The recorded data shows a consistent pattern: the AMD A10-7870K wins every single benchmark in the head-to-head comparison, taking all 5 recorded tests. Its average benchmark score is 975 compared to 962 for the A8-9600, a 1.4% overall advantage. Both CPUs sit at the 26th percentile among all processors, meaning they occupy similar performance tiers despite the older architecture.

For users who prioritize raw compute performance, the A10-7870K is the clear choice. It delivers 6.4% higher multi-core scores in Cinebench R15, R20, and R23, and 6.6-6.7% higher single-core scores. The unlocked multiplier adds flexibility for those willing to push beyond stock speeds.

The A8-9600, however, offers a lower 65W TDP compared to 95W for the A10-7870K, which matters for compact builds or systems with modest cooling. It also supports DDR4 memory with 38.4 GB/s bandwidth versus 34.1 GB/s for the DDR3-based A10-7870K. The A8-9600 uses the AM4 socket, which has broader platform compatibility, while the A10-7870K uses the older FM2+ socket.

Practical guidance: if you already own an FM2+ board and need the fastest available compute performance, the A10-7870K is the superior pick from the data. If you are building on AM4 with DDR4 memory and prefer lower power draw, the A8-9600 is the sensible choice, accepting a modest performance deficit.

Head-to-Head Benchmarks

The A10-7870K wins all five recorded comparisons. The margin is remarkably consistent across both multi-core and single-core workloads.

In Cinebench R15 multi-core, the A10-7870K scores 299 versus 281 for the A8-9600, a 6.4% lead. The same 6.4% margin appears in Cinebench R20 multi-core, where scores are 1249 and 1174 respectively. Cinebench R23 multi-core shows 2975 against 2797, again a 6.4% advantage.

Single-core results follow the same pattern. Cinebench R20 single-core gives the A10-7870K 176 points versus 165 for the A8-9600, a 6.7% edge. Cinebench R23 single-core shows 420 versus 394, a 6.6% margin.

These consistent deltas indicate the performance gap is structural, not workload-specific. The A10-7870K's higher clock speeds, 3.90/4.10 GHz versus 3.10/3.40 GHz, explain the uniform advantage. The A8-9600 cannot overcome this frequency deficit despite its newer architecture and higher transistor count.

It is worth remembering the A10-7870K also has additional benchmark data available: Geekbench multi-core at 1225 and single-core at 478. The A8-9600 lacks corresponding Geekbench results in the database, so no direct comparison is possible for those tests.

Specification Differences

The two processors diverge on nearly every physical and electrical specification.

Clock speeds differ substantially: the A10-7870K runs at 3.90 GHz base and 4.10 GHz boost, while the A8-9600 sits at 3.10 GHz base and 3.40 GHz boost. This is roughly a 26% frequency advantage for the A10-7870K at base clocks.

Power consumption favors the A8-9600, which draws 65W TDP versus 95W for the A10-7870K. That is a 46% reduction in thermal design power.

Sockets are incompatible: the A10-7870K uses AMD Socket FM2+, while the A8-9600 uses AMD Socket AM4. This means they cannot be swapped between the same motherboards.

Memory support differs by generation. The A10-7870K uses DDR3 with 34.1 GB/s bandwidth; the A8-9600 uses DDR4 with 38.4 GB/s bandwidth. Both are dual-channel.

PCIe connectivity also differs. The A10-7870K provides Gen 3 with 16 lanes (CPU only), while the A8-9600 provides Gen 3 with 8 lanes (CPU only). The A10-7870K has double the CPU-attached lanes.

Cache configuration varies: the A10-7870K has 256 KB L1 and 4 MB L2, while the A8-9600 has 320 KB L1 and 2 MB L2. The A10-7870K has double the L2 cache, though the A8-9600 has more L1.

The A10-7870K has an unlocked multiplier; the A8-9600 does not. Production status also differs, with the A10-7870K marked End-of-life and the A8-9600 Active.

Architecture Differences

The A10-7870K uses the Steamroller architecture, codenamed Godaveri, from the A10 generation. The A8-9600 uses the Excavator architecture, codenamed Bristol Ridge, from the A8 generation.

Both are built on a 28 nm process at GlobalFoundries. Despite the same node, the A8-9600 integrates more transistors: 3,100 million versus 2,411 million for the A10-7870K. Die sizes are close, at 250 mm² and 245 mm² respectively, meaning the A8-9600 has a higher transistor density.

The cache hierarchy differs in organization. The A10-7870K allocates 256 KB L1 and 4 MB L2, while the A8-9600 provides 320 KB L1 but only 2 MB L2. Neither processor includes L3 cache. This means the A10-7870K relies on a larger L2 pool, while the A8-9600 compensates with a slightly larger L1.

Both processors integrate Radeon R7 graphics, though the underlying GPU architecture likely differs with the overall CPU generation. The A10-7870K has a wider PCIe interface at 16 lanes versus 8 lanes for the A8-9600, which may affect discrete GPU bandwidth on the respective platforms.

Memory controller differences are inherent to the DDR3 versus DDR4 split. The A8-9600's DDR4 support enables higher theoretical bandwidth, but the recorded benchmark data does not show this translating into compute performance wins.

Where Each One Wins

The A10-7870K wins everywhere in the recorded benchmarks. It takes all 5 head-to-head tests, covering multi-core and single-core workloads across three Cinebench versions. The margins range from 6.4% to 6.7%, with single-core showing slightly larger deltas than multi-core.

The A10-7870K is the better choice for compute-bound tasks such as rendering, video encoding, or any workload that scales with CPU frequency. Its 16 PCIe lanes also make it more suitable for systems with a discrete GPU, since the CPU can feed the graphics card with full bandwidth.

The A8-9600 does not win any benchmark, but it has situational advantages outside raw performance. Its 65W TDP allows for simpler cooling solutions and lower power bills. The AM4 socket provides a modern platform with DDR4 memory support, which may offer better upgrade paths. The 38.4 GB/s memory bandwidth is higher than the A10-7870K's 34.1 GB/s, though this does not appear in the recorded performance data.

For users building a low-power home server or a basic desktop where energy efficiency matters more than peak compute, the A8-9600 is the defensible pick. For anyone who wants maximum performance from these two options, the A10-7870K is unequivocally faster according to the database.

The A8-9600's active production status means it remains available for new builds, while the A10-7870K is end-of-life. This favors the A8-9600 for long-term system planning, but the performance data still favors the older part.
