I'm building a destkop and working somewhat on a budget. I have came down to 2 CPUS that I can choose from. I need to know which one of these CPU's would perform better and faster. The AMD APU A8 - 7600 or the Intel i3 - 4160? The AMD has more cores but on certain websites I see that they say that the Intel out performs the AMD. This to me is very strange as the AMD has more cores.

Also, if I buy an AMD FX processor, do I need to buy a GPU for displaying my screen, because I dont see that the FX has graphics. Correct me on this if I'm wrong.

NOTE: I'm mainly going to use this computer for computing numbers, working out mathmatical stuff and do a lot of intesive encrypting and decrypting of my network data etc... Not really graphics at all.

Short answer: for heavy single-thread number crunching and AES-style encryption, the Intel Core i3‑4160 is the safer pick; its Haswell core has stronger per‑core throughput and ships with AES instruction support that many crypto libraries will use for big speedups. If the workload is embarrassingly parallel and can use four full cores simultaneously, an A8‑7600 (or a larger FX/Ryzen part) can sometimes win — but that’s workload dependent. (intel.com)

What the two chips actually are: the i3‑4160 is a 2‑core/4‑thread Haswell desktop part at 3.60 GHz with Intel HD4400 graphics, DDR3‑1333/1600 support and Intel AES New Instructions. The A8‑7600 is a Kaveri APU: 4 physical cores (4 threads), 3.1–3.8 GHz, Radeon R7 integrated graphics and support for faster DDR3 (up to DDR3‑2133). Benchmarks from the period show the i3 ahead in single‑thread tests while the A8 can be closer in multi‑threaded/graphics tasks. (intel.com)

On the FX question: AMD FX desktop CPUs do not include on‑chip graphics, so a discrete GPU (or a motherboard/CPU combo with an APU) is required to get video output. If using an AMD APU, populate matched dual‑channel memory and choose higher DDR3 speeds (e.g., 1866–2133) to help the integrated GPU and memory‑bound routines. Also confirm that your crypto stack (OpenSSL, libs) is using AES hardware acceleration on install. (cpu-monkey.com)

Practical pick for your stated use (math + heavy encrypt/decrypt, not graphics): go i3‑4160 (or a modern used quad with good per‑core performance). If you expect many threads that parallelize perfectly, consider a true 4+ core CPU, but not an FX unless you plan a discrete GPU and a compatible AM3+/FM2+ motherboard. Check motherboards/sockets (LGA1150 vs FM2+) and buy dual‑channel RAM kits. (intel.com)

I prefer Intel than AMD and suggest you too.

Let me rather rephrase the question:

For heavy number crunching, which is better, AMD or Intel?

get the a8 .. its not noticably slower than the i3 in general computing but is noticably better in anything graphical .. n plz pair it with 1866 Mhz ram as integrated gfx of amd will use system ram ..

I3

intel is better for performance, but AMD is better for graphical performance. I prefer INTEL but I love AMD :D
