AMD Athlon 64 X2 4600+ EE

The AMD Athlon 64 X2 4600+ EE is a desktop processor from AMD built on the K8 architecture with the Windsor codename. Released on 2006-05-22 for the AMD Socket AM2 platform, it pairs two cores with two threads at a fixed 2.40 GHz base clock and no boost capability, drawing a 65 W TDP. The silicon is fabricated on a 90 nm process with 154 million transistors across a 220 mm² die. The cache layout provides 256 KB of L1 and 512 KB of L2 with no L3 and no 3D V-Cache. Memory access runs over a dual-channel bus without ECC support, and PCIe Gen 2 is available. The database records no benchmark scores for this part, leaving a 50th-percentile rank against all CPUs as its only positional metric.

Platform and Compatibility

The Athlon 64 X2 4600+ EE is bound to the AMD Socket AM2 interface, which determines the motherboards it can be installed into and the upgrade path available to owners. The K8 architecture and Windsor codename define the microarchitecture generation, and the 90 nm process with 154 million transistors on a 220 mm² die gives a physical footprint that fits AM2 sockets of the period. The memory controller supports a dual-channel memory bus; the specific memory types are not recorded in the database, and ECC memory is not supported, so error-correcting memory modules cannot be used. Expansion is provided through PCIe Gen 2, which is the interconnect generation available on this platform.

Integrated graphics are not built into the processor; the fact pack indicates that display output is available "on certain motherboards" as a chipset feature, meaning any video output depends on the motherboard's integrated chipset rather than the CPU. The part is classified in the desktop market segment and is end-of-life, with a release date of 2006-05-22. The multiplier is locked, so the 2.40 GHz base clock cannot be raised through multiplier adjustment; the part number ADO4600IAA5CU identifies this specific SKU. The 65 W TDP defines the thermal and power delivery requirements for a system build. Because the processor is end-of-life, new units are no longer manufactured, and any upgrade from this platform requires a motherboard and processor change, as the AM2 socket and its chipset define the compatible hardware envelope.

Who Should Consider It

The quantitative picture for the 4600+ EE is limited: the benchmarks array is empty and the average benchmark score is 0, so the 50th-percentile rank against all CPUs in the database is the only performance indicator. A 50th percentile places the processor exactly at the median of the database population — above half of all CPUs and below half. For a dual-core, dual-thread part with a 2.40 GHz fixed clock and 256 KB L1 / 512 KB L2 cache, this median position indicates suitability for workloads that do not demand high thread counts or high peak frequencies.

Office productivity, web browsing, and document editing are well matched to a two-thread design, since these tasks typically use one or two threads and do not require large caches. Gaming is a mixed case: older titles that rely on a single thread can use the 2.40 GHz clock, but modern games that expect more than two threads will exceed the processor's capabilities; the database provides no game-specific scores to refine this. Content creation workloads such as video encoding and 3D rendering scale poorly on a two-thread part, as these applications benefit from higher core counts and larger caches; the absence of an L3 cache and the 512 KB L2 limit the working set that can reside on-die. The dual-channel memory bus provides a moderate bandwidth path, but without L3, memory latency becomes more visible when the L2 cache misses. The 65 W TDP makes this a low-power option for systems where thermal output matters, and the fixed 2.40 GHz clock means power draw is steady under sustained load. The end-of-life status means it is relevant only to legacy systems or collectors, not new builds.

Single-Thread vs Multi-Thread Behavior

The 4600+ EE has a clear behavioral split between single-threaded and multi-threaded execution. It contains two cores and two threads, with no simultaneous multithreading, so the thread count equals the core count. The 2.40 GHz base clock is the maximum frequency; there is no boost clock, so the processor runs at 2.40 GHz regardless of load. This fixed frequency is a benefit for single-threaded code that responds directly to clock speed, but it also means the processor cannot temporarily raise its clock to accelerate one active thread.

The cache hierarchy shapes both behaviors. The 256 KB L1 and 512 KB L2 are the only on-die storage, with no L3 cache present. For single-threaded workloads, the L1 and L2 caches hold the full working set of the active thread. When both threads are active, the two threads share the same L1 and L2 resources, effectively halving the available cache per thread. The dual-channel memory bus is the shared path to system memory, and without an L3 cache to buffer traffic, memory latency becomes a factor on L2 misses. The dual-channel memory bus designation indicates the memory path available to the processor, though the specific memory bandwidth is not recorded in the database. In summary, single-thread performance is driven by the 2.40 GHz clock and the K8 pipeline, while multi-thread performance is capped at two threads and constrained by shared cache and memory bandwidth.

How It Compares

The database contains no nearest rival entries for the 4600+ EE; the nearestRivals array is empty. As a result, there are no rival names, rival scores, or delta percentage values to report in this comparison. The only comparative reference available is the 50th-percentile rank against all CPUs in the database, which places this processor at the median of the entire CPU population. This percentile is a relative rank, not a performance score, and given that the average benchmark score is 0 and the benchmarks array is empty, the percentile is likely a default placement rather than a measured outcome.

Without rival data, a direct head-to-head comparison is not possible from the available facts. The processor's position must be inferred from its architectural specifications: two cores, two threads, a 2.40 GHz fixed clock, 256 KB L1, 512 KB L2, no L3, and a dual-channel memory bus. These characteristics define a dual-core desktop part from the K8/Windsor generation, but the absence of rival entries means no quantitative comparison can be made in this analysis. Any statement about how this processor performs relative to a specific competitor would require data that the database does not provide.

Benchmark Performance

Benchmark performance for the 4600+ EE cannot be expressed through measured scores, because the benchmarks array is empty and the average benchmark score is 0. The only numeric performance-related field is the percentile vs all CPUs, which is 50. A 50th percentile means the processor sits exactly at the midpoint of the database's CPU distribution: it ranks above 50% of CPUs and below 50% of CPUs. However, because the average benchmark score is 0, this percentile is not supported by any actual benchmark runs recorded in the database. The empty benchmark record means the percentile is a positional placeholder, not a performance measurement.

The architectural data provides the only basis for performance expectations. The 2.40 GHz base clock, fixed with no boost, sets a hard ceiling on single-thread throughput. The two cores and two threads cap multi-threaded throughput at two concurrent threads. The 256 KB L1 and 512 KB L2 caches, with no L3, limit the on-die working set; workloads that exceed the L2 capacity will generate memory traffic over the dual-channel memory bus. The 90 nm process, 154 million transistors, and 220 mm² die size are manufacturing characteristics that influence thermal and power behavior, and the 65 W TDP reflects the power envelope of this design. The lack of ECC memory support and the locked multiplier further define the operating envelope. In aggregate, the data indicates a processor positioned at the median of the database population, with no measured scores to refine that position. The 50th percentile, combined with the dual-core, 2.40 GHz configuration, suggests a part that was mainstream at its 2006-05-22 release, but the empty benchmark record means this analysis cannot quantify its standing against any specific rival.
