CPU history back to back: Intel vs AMD

It is about the modern processor history, mind you, the one since 1970s until now, not the one from 1826, when the differential engine was built or since 1600s, when a tax calculator was devised by Pascal or from way back before when the Chineze were using the abacus.

Intel first launches the 4004 CPU and then the 8086 with x86 architecture. After this it launched the 286, 386, Pentium I and so on.

Intel highlights:
– Intel 386dx = first to use 32 bit X86 processor, 33MHz, 4 GB RAM
– Intel Pentium = first to add MMX, multimedia extension
– Celeron 300A = first to let you overclock the processor
– Pentium III = speedstep, run the CPU at lower speeds when idle, add L2 cache, first over 1GHz
– 2002 = added hyperthreading technology
– 2004 = LGA type socket, contact pins on the motherboard, not on the CPU chip
– 2006 = Core Duo and Quad see the daylight, the end of “Gigahertz war”, added virtualization and turboboost, onboard videocard
– since then 10-15% improved performance each passing year

Now, AMD started by copying Intels 8080 processor, but then moved on to creating their own CPU and also developing X64 processors which them they licenced to Intel in order to further fuel the CPU wars:

AMD highlights:
– 1974 = AM9080 was a clone of Intel 8080
– 1976 = Intel licenced to aMD the X86 architecture
– 1996 = AMD K5 designed to fight with Pentium I
– 1997 – 1998 = AMD K6-2 captured a good chunk of the PC market
– 1999 = AMD K7/Athlon, first to run at 1GHz, used the PR rating system like 1900+ (relative to Intel processor speeds)
– 2003 = AMD lunches X86-64 architecture in K8 series (64bit processors)
– 2005 = multicore processing
– APU, FX series is created = APU has added video on board, FX for gaming, comparable to Intel

What is HBM, the new memory type used in video cards [High Bandwidth Memory]

GDDR5 is history. Or at least it will be history, as HBM, High Bandwidth Memory, is able to provide at least two times more throughput than its predecessor. GDDR5 is over 7 years old now and has the memory chips attached directly to the video card’s PCB, around the GPU. If you needed more GDDR5 memory, then you would need more such chips inserted in there and more connections to the GPU.

HBM solves this issue by stacking the memory chips on top of the GPU package, the area that holds the GPU, so it doesn’t need anymore extra space than the GPU already needs. It stacks the memory in 3D RAM dies right next to the GPU which makes communication with it much much faster.

With 4 stacks of HBM you can get about 1TB/s transfer rate. Right now only AMD Radeon R9 Fury series has this type of memory, but many other video cards with HBM will be available soon.

AMD vs Intel smackdown: Intel is better, but about 30% pricier

The answer is short: Intel is better because it has invested more into processors than AMD. AMD delivers almost the same performance for the same cost, however it is cheaper.

So, if you have money to spend, buy an Intel i7 newest generation. If money are an issue, then try to buy an AMD FX 8300 or the like. When it comes to gaming you need to remember one thing: the single most expensive piece of hardware needs to be the video card. That one pulls harder when its about video games.
