This is a relatively narrow range which indicates. The reason of these "cores" bad performance is more related to that each ALU cluster ("cores") only feature 2 ALUs and 2 AGUs, compared to haswell which feature 4 ALUs and 4 AGUs per ALU cluster. The range of scores (95th - 5th percentile) for the AMD FX-6300 is just 18.3. However in most workloads, these "cores" can work without interferings. In these cases the CMT architecture will bottleneck, and course these "cores" to fight over resources. It would mostlikely be heavy AVX workloads or heavy memory workloads. It is only in certain workloads that these two ALU cluster (what people mention as AMD's bulldozer "cores") will be fighting over resources. Based on 366,465 user benchmarks for the AMD FX-6300 and the Intel Core i5-3570, we rank them both on effective speed and value for money against the best 1,417 CPUs. In reality the module is the actual physical core. In bulldozer and piledrivers case we are talking about duplication of the ALU cluster. CMT is basically duplicating certain parts of a core. there is only 1 sheet of paper and 1 pen to use between both students, and they are fighting over the use of it) AMD's bulldozer architecture feature the core technology called CMT. (to give a analogy, its like giving a complex math problem to 2 students in which requires a pen and paper to figure out. This makes the 2 cores fight each other for resources, making they far less efficient. It puts 2 cores inside 1 module, as opposed to 1 core per module. So its less cores than a quad core with hyperthreading. This actually increases the performance of the cpu by about 8-12%. So a fx4300 is seen as a 2core/4thread cpu, f圆300 is seen as a 3core/6thread cpu and a 8350 is a 4core/8thread cpu by windows. What that patch does is make windows see the bulldozers modules as cores. AMD FX-6300 Six-Core Description: Class: Desktop Socket: AM3+ Clockspeed: 3.5 GHz Turbo Speed: 4.1 GHz Cores: 6 (in 3 physical modules) Typical TDP: 95 W Cache Size: L1: 480 KB, L2: 12. (it was a patch for windows 7, but automatically included in 8). Is the AMD FX-6300 Six-Core Good for Gaming This is a fairly old CPU that is no longer competitive with newer CPUs. It includes the amd bulldozer patch already. The reason windows sees it as a 3 core processor, is because windows 8 was designed that way. Except intels hyperthreading is software based, where as the bulldozer is hardware based since there are physical cores. it works similar how intel has hyperthreading in which it gives 2 threads per core. its would be essentially a 3 core cpu with 6 threads. So the f圆300 has 6 cores 3 modules and 6 threads. there is only 1 sheet of paper and 1 pen to use between both students, and they are fighting over the use of it) The amd bulldozer architecture is different from most traditional architectures for cpus.
