some guys says its just 4 cores .
and each one of them has 2 modules or whatever. i dont know what they are saying but i get their point that theyre saying amd fx 8350 is just 4 cores CPU. my question is ... is that true ?

no, 8 cores, 8 threads

yes. it is 4 cores, but it has hyperthreading so that means that each core can act as 2. so it has 8 threads(virtual cores) but 4 real cores. however, that is more than enough these days.

The AMD FX-8350 has 4 modules with 2 cores in each module. Each 2 cores in the module will share resources. Yes, there are 8 cores in total, but they are not separate, and are not hyper-threading. This is a good cost saver for AMD.
Intel quad-core CPUs will have 4 modules with a core in each module.

Ill take a sec to answer this thread properly. An FX CPU is made up of "modules" that each consist of 2 integer processing units and one floating point unit. So an 8 "core" FX does indeed have 8 processing cores sharing 4 floating point units. This is by far superior to hyperthreading as these are actual real stand alone processing units unlike hyper threading. 4 core = 2 module, 6 core = 3 module, 8 core = 4 module.

It's, err, well it's kinda both 4 and 8 core. Here: http://www.tomshardware.com/reviews/fx-8150-zambezi-bulldozer-990fx,3043-3.html

You are confusing the AMD FX-8350 and the Intel Core i7 (all models) CPUs. There are 8 physical cores in the FX-8350. There are basically two versions of the desktop Core i7 CPUs; quad core and the more expensive 6 core versions. Both have Hyper Threading which means each physical core also has a virtual (or logical) core. Thus Core i7 CPUs are either 4 cores and 8 threads or 6 cores and 12 threads.

The problem with the FX CPUs is that it is a modular design. Every two physical CPUs shares a single FPU (Floating Point Unit). If both CPUs must use the FPU in each module, then one core basically needs to wait and do nothing until the other core is done using the FPU. Therefore, the FPU itself is a performance bottleneck.

Actually hyper-threading is far better because the 2 "modules" in each AMD FX core are bulldozer cores with an absolutely terrible IPC (instructions per-cycle) that's why Intel's processors outperform AMD in almost all benchmarks and real world tests.

No hyper-threading and CMT are not directly competing, as they are in use for different purpose.

Hyperthreading works to increase performance efficiency and increasing throughput.

Where the cluster-architecture(modules) are trying to be space-efficient and tries to cut out many of the redundant parts of a core.

The cluster-architecture are proven to have more performance gain than hyper-threading.

EDIT: I think you got it wrong, it is 2 cores in 1 module.

AMD dont use "hyperthreading" thats an intel gimmick
