HT Vs HT

[Taxation]

The 2 cpu manufacturers have some different technologies,
theres intel's HT
and AMD's HT

intel
hyper threading

AMD
hyper transport

both are very different
intels hyper threading
an intel cpu with hyper threading turns one physical core into 2 virtual cores.The processor can work on two sets of tasks simultaneously, use resources that otherwise would sit idle, and get more work done in the same amount of time.

AMD hypertransport
HyperTransport technology is a high-speed, low latency, point-to-point link designed to increase the communication speed between integrated circuits in computers, servers, embedded systems, and networking and telecommunications equipment up to 48 times faster than some existing technologies.
HyperTransport technology helps reduce the number of buses in a system, which can reduce system bottlenecks and enable today's faster microprocessors to use system memory more efficiently in high-end multiprocessor systems.
HyperTransport technology is designed to:
Provide significantly more bandwidth than current technologies
Use low-latency responses and low pin counts
Maintain compatibility with legacy PC buses while being extensible to new SNA (Systems Network Architecture) buses.
Appear transparent to operating systems and offer little impact on peripheral drivers

Intel
a 3.6ghz cpu can be beaten by a 3.02 ghz cpu that has HT technology when loading programs
AMD
All AMD cpu's have HT technology, so theres no differences like the intel cpu's have.

Intel vs AMD
Its all about the numbers
Or is it??

An AMD 64 3000+ running at 2ghz can beat a 3ghz intel processor (even with HT) at certain scenarios.
in doom3 the AMD cpu beats a 3ghz intel cpu by 19 frames(now im no expert but thats alot)
But in multi tasking the intel cpu beats the AMD cpu by a considerable amount.

AMD cpu's have always been the best choice for gaming (as shown in the doom 3 results, 19fps is quite a high amount just being done by the cpu)

in 3dmark 2005 the AMD beats the intel cpu by 673 marks
but in the pcmark2005 the intel wipes the floor with the amd cpu by over 1000 marks

This shows that both cpu's have their highs and lows.
Tests shown here were done with a
3.06ghz pentium 4
AMD 64 1.8ghz newcastle core

suggestions
AMD for gaming
Intel equivelant for everything else

amd 64 3000=3ghz intel etc

[djgandy]

If only amd made 3ghz cpu's....

[Taxation]

If they did that then they would have to disable all of the technologies that make AMD's much better at gaming

Hi, I've just joined so forgive me for raising a 2 year old post, though it is on the first page!!! :wink:

How do AMD and Intel size up to each other these days what with both of them having dual and quad core processors on the market?

[Jonny2Bad]

Intel all the way for both dual and quads, amd are starting to get a little better but not much unfortunately.

[Nox]

yep Intel are... in short... better.

Do AMD offer better value still assuming you don't bring overclocking into it still?

Nox

[Jonny2Bad]

No i dont think they do offer better value, they are cheaper because they arent quite cutting it yet, unfortunately i would love amd to get their act together we would then be getting better deals from both sides, im not an intel fan or an amd fan, as ive said b4 im a me fan i want the best i can afford.

AMD's processors work more like GPU processors rather than pure CPU where as Intel processors are purely designed for the purpose of being a mainboard CPU

They do?

[PeteA]

Well their architecture is more like GPU architecture. I don't know why AMD have done this but it seems to work for some applications. I suppose it's really because back in the day when graphics cards didn't have all this power the cpu handled more of the processing where as now its more separated and they haven't really gone away from that. If you look at the 3d mark scores as Tax pointed out AMD's will beat Intel CPU's when running graphics through them.

[djgandy]

I don't see how it is more GPU like. GPU's have hundreds of cores and are designed for parallelism and number crunching.
AMD's uarch is not a lot different to Intel's. The main differences are no FSB and an Integrated memory controller.

[PeteA]

I was told that by someone from Intel although thinking about it and doing some more research, pretty much ignore what I just said. Probably some rivalry talk to get me to buy Intel instead of AMD. I also remember some of the things he came out "AMD use out dated technology". Which technically they do but it works for them. They're using bigger layers than intel now and bigger packages, but the advantage they do have is less power consumption.

An interesting read.

Although it does look like AMD are going to put the CPU and GPU on the same dye

[djgandy]

Intels power consumption is far better than AMD's. AMD do have the MC onboard though so that takes a bit of extra power. Both of those articles are quite out of date so I doubt they include any of Intels products released in the past 2 years.

AMD do use a bigger die which is why Barcelona is such a piece of ****. It is outside of the generally accepted norm for die size. Large die mean poorer yields (hence the X3) and also less flexibility.

Basically AMD tried to be too clever and have shot themselves in the foot.

Intel are putting CPU/GPU on same die too. Nehalem will feature that, likely before AMD's effort turns up.

[PeteA]

Yeah the Barcelona is really excrement.

Hopefully Intel's 80 core processors will be out and then we just need the operating systems to deal with threading (in the true sense, not the current with is make it look it's multitasking)
