Q: Are both processors from the same manufacturing node?

A: No. The AMD A8-6600K is built on a 32 nm process at GlobalFoundries, while the Intel Core i5-3230M uses Intel's 22 nm process. The Intel chip also has a smaller die size at 118 mm² compared to AMD's 246 mm².

Q: Which processor has more cache?

A: The AMD A8-6600K has 192 KB of L1 cache and 4 MB of L2 cache. The Intel Core i5-3230M has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 3 MB of shared L3 cache. The AMD chip has no L3 cache, while Intel's design includes it.

Architecture Differences

The AMD A8-6600K is built on the Piledriver architecture, specifically the Richland codename, using a 32 nm process at GlobalFoundries. It is a desktop part with 4 cores and 4 threads, running at a 3.90 GHz base clock and 4.20 GHz boost clock. The chip integrates a Radeon HD 8570D graphics unit and supports dual-channel DDR3 memory with a bandwidth of 29.9 GB/s. It uses an AMD Socket FM2 and has an unlocked multiplier, allowing overclocking.

The Intel Core i5-3230M is based on the Ivy Bridge architecture, also known as Ivy Bridge codename, manufactured on Intel's 22 nm process. This is a mobile processor with 2 cores and 4 threads, running at a 2.60 GHz base clock and 3.20 GHz boost clock. It integrates Intel HD 4000 graphics and supports dual-channel DDR3 memory, though the database does not record a memory bandwidth figure. It uses an Intel Socket G2 (988B) and has a locked multiplier.

The manufacturing process difference is significant: Intel's 22 nm node is smaller than AMD's 32 nm node, and the Intel die measures 118 mm² compared to AMD's 246 mm². The AMD chip uses 1,303 million transistors, while the database does not list a transistor count for the Intel part. The cache layouts differ fundamentally: AMD uses a larger L1 (192 KB total) and 4 MB of L2, but no L3; Intel uses per-core L1 and L2 allocations plus a 3 MB shared L3 cache.

The AMD processor has a much higher TDP at 100 watts versus 35 watts for Intel, reflecting its desktop orientation and higher clock speeds. The AMD chip is end-of-life in production status, while the Intel part has no recorded production status. Release dates show the AMD part arriving on 2013-05-31 and the Intel part on 2012-12-31, meaning Intel's chip came to market roughly five months earlier.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these processors, and the results split evenly. In Geekbench multi-core, the AMD A8-6600K scores 1076 against the Intel Core i5-3230M's 1018, giving AMD a 5.7% win. This margin is modest but consistent with the AMD chip having twice the physical core count. The extra cores help in multi-threaded workloads, even though both chips present the same 4 threads to the operating system.

In Geekbench single-core, the Intel Core i5-3230M takes the lead with a score of 505 versus AMD's 451, a 10.7% advantage for Intel. This is a more substantial margin than AMD's multi-core win, indicating that Intel's Ivy Bridge architecture delivers better per-core efficiency despite the lower clock speeds. The Intel chip's boost clock of 3.20 GHz is a full 1.00 GHz lower than AMD's 4.20 GHz, yet it still wins the single-core test, which points to superior IPC (instructions per clock) from the Intel architecture.

Looking at the broader benchmark database, the AMD A8-6600K has an average benchmark score of 764, while the Intel Core i5-3230M averages 754. Both chips sit at the 20th percentile when compared to all CPUs in the database, meaning they are roughly equivalent in overall standing. The AMD chip's nearest rivals include the Intel Core i7-3537U with an average score of 766 (a 0.3% difference), the Intel Core i3-3240 at 761 (0.5% ahead of AMD), and the Intel Core i5-3210M at 758 (0.8% behind AMD). The Intel Core i5-3230M's nearest rivals include the Intel Xeon X5460 at 754 (exact match), the Intel Core i5-4250U at 756 (0.2% ahead), and the Intel Xeon E5450 at 756 (0.3% ahead).

The Intel Core i5-3230M also has additional Cinebench scores recorded in the database, which the AMD A8-6600K lacks. These include Cinebench R15 multi-core at 220, Cinebench R20 multi-core at 917, Cinebench R20 single-core at 129, Cinebench R23 multi-core at 2184, and Cinebench R23 single-core at 308. These numbers provide context for the Intel chip's capabilities but do not allow direct comparison since the AMD part has no corresponding scores.

Specification Differences

The two processors differ across nearly every major specification category. The AMD A8-6600K has 4 cores and 4 threads, while the Intel Core i5-3230M has 2 cores and 4 threads. Base clocks are 3.90 GHz versus 2.60 GHz, and boost clocks are 4.20 GHz versus 3.20 GHz, with AMD higher in both cases.

TDP is a major differentiator: 100 watts for AMD versus 35 watts for Intel. The sockets are incompatible: AMD Socket FM2 versus Intel Socket G2 (988B). The manufacturing nodes differ at 32 nm versus 22 nm, and die sizes are 246 mm² versus 118 mm². The AMD chip uses 1,303 million transistors, while the Intel chip has no recorded transistor count.

Cache configurations are structurally different. AMD has 192 KB of L1 and 4 MB of L2, with no L3. Intel has 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3. Memory support is DDR3 for both, and both use dual-channel memory buses. The AMD chip has a recorded memory bandwidth of 29.9 GB/s, while Intel's bandwidth is not recorded in the database.

The integrated graphics differ: AMD uses Radeon HD 8570D, Intel uses Intel HD 4000. The AMD chip has an unlocked multiplier, while Intel's is locked. Market segments are desktop for AMD and mobile for Intel. The AMD part is end-of-life, while Intel's status is not recorded. PCIe support is listed as Gen 2 for AMD, with no PCIe data for Intel.

Where Each One Wins

The AMD A8-6600K wins in multi-core workloads according to the Geekbench multi-core test, where it holds a 5.7% lead over the Intel Core i5-3230M. This advantage comes from its 4 physical cores and higher clock speeds, making it the better choice for applications that scale with thread count. The unlocked multiplier also gives it overclocking headroom, which the Intel chip cannot offer. As a desktop processor with a 100 watt TDP, it is suited for systems where power consumption is not a primary constraint.

The Intel Core i5-3230M wins in single-core performance with a 10.7% lead in Geekbench single-core. This indicates that Intel's Ivy Bridge architecture delivers better per-thread performance, which benefits lightly threaded applications such as older games, everyday productivity, and tasks that rely on a single dominant thread. The Intel chip also has a dramatically lower TDP at 35 watts, making it the clear choice for laptops or compact systems where heat and battery life matter. The presence of a shared L3 cache is another advantage for Intel, as it can improve performance in certain workloads that benefit from faster access to larger cache pools.

For memory bandwidth, the AMD chip has a recorded advantage with 29.9 GB/s, while Intel's bandwidth is not specified in the database. This suggests AMD may have an edge in memory-intensive tasks, though the lack of an Intel figure prevents a direct comparison.

The Verdict

The recorded data paints a clear picture: the AMD A8-6600K and Intel Core i5-3230M trade blows, with each winning one of the two direct benchmark comparisons. The AMD chip takes multi-core by 5.7%, and the Intel chip takes single-core by 10.7%. The larger single-core margin suggests that Intel's architectural efficiency outweighs AMD's clock speed advantage in per-thread performance.

The choice between these two processors should be guided by the use case. For a desktop build where multi-threaded performance and overclocking are priorities, and where power consumption is not a concern, the AMD A8-6600K is the stronger option. Its 4 cores, 100 watt TDP, and unlocked multiplier make it a reasonable choice for budget-conscious builders focusing on multi-core tasks.

For a laptop or any power-constrained system, the Intel Core i5-3230M is the only sensible pick. Its 35 watt TDP is less than half of AMD's, and its single-core lead matters for everyday responsiveness. The Intel chip also benefits from the 22 nm process, which is more modern than AMD's 32 nm node, and it includes a shared L3 cache that AMD lacks.

Both processors sit at the 20th percentile in the database, and their average scores are close: 764 for AMD versus 754 for Intel. The Intel chip's nearest rival is the Intel Xeon X5460 with an exact score match, while AMD's nearest rival is the Intel Core i7-3537U, less than 1% away. This indicates that neither chip is a standout in its class, but each serves a distinct market segment: desktop versus mobile. Choose AMD for raw multi-core throughput and overclocking, choose Intel for efficiency and single-core performance.
