what is that mean hypertransport or hyperthreading?

unsa mai nka lain aning duha plan to buy intel or amd platform

mao cguro ni ang explanation bro

Hyperthreading Technology (by intel) is where the intel processors make a virtual processor, much like how daemon tools or alcohol makes a virtual dvd rom drive. It makes the computer act as though there is an extra processor and that helps with handling some of the data being processed. You can read the defition here at WikiPedia Hyper-threading - Wikipedia, the free encyclopedia. that is the best and easiest to understand that i have found..

HyperTransport (AMD) is where the processor reduces the number of buses in a system by improving communication and data transfer between components of the motherboard and CPU etc. It helps to reduce bottlenecks which reduce system performance. Wikipedia has a definition here HyperTransport - Wikipedia, the free encyclopedia and Alienware has an easier definition here http://4help.alienware.com/cgi-bin/a...i=&p_topview=1

+1 to bbriones

in short either way intel (perf) or amd (cheaper) ang user ang panalo

[regilsolon]

fyi.

in contrast to intel hyperthreading to amd is not hypertransport but amd true core scalability

Intel Hyper-Threading vs. AMD True Core Scalability | AMD at Work

In light of this, AMD’s labs have performed experiments to quantify how much better performance scales when using true AMD cores than when using Intel Hyper-Threading. The charts below show the performance scaling of servers using AMD Opteron™ processor Model 6136 (8-core 2.4GHz) and Intel Xeon processor (“Nehalem”) Model X5570 (4-core 2.93GHz). The bars on the left below show relative performance when using 8 copies in a two-socket server (four copies per processor). The bars on the right below show how much performance increases in the same server when using 16 copies in a two-socket server (8 copies per processor)

nice, mao diay na counter part sa HT sa intel.

Wala na ko nagsubaybay unsa ang tech updates sa amd... sa desktop wala pay nakalamang sa i7 atm

@OT: Mas daghan core/thread mas daghan mu-"trabaho" sa imoha gusto. Mas faster mahuman.

so kung naa ka cash go for i5/i7 kung gusto ka barato go for x2/x4/x6

Intel is also planning to implement REVERSE HYPERTHREADING technology called “Anaphase”.

check this out.

Hyper-threading is an Intel-proprietary technology used to improve parallelization of computations (doing multiple tasks at once) performed on PC microprocessors.
Hyper-threading - Wikipedia, the free encyclopedia

in reality.its not just intel. amd had its own COUNTER version of intel's Hyperthreading.. its an old talk already.
can't dig the page in Tomshardware about an article of this but the closest of the story is this: AMD to do HyperThreading? ? Computer Chips & Hardware Technology | Geek.com

"The Inquirer speculates that AMD may be investigating implementing some sort of symmetric multithreading (or SMT, the technical industry term for processing multiple threads in one processor, called “HyperThreading” by Intel) for the upcoming Athlon 64 series of processors, although there has been no evidence of that to date

^^ a solution shown by regisolons post..

even SUN | IBM and Cray had its own version..

Simultaneous multithreading - Wikipedia, the free encyclopedia

and

hypertransport:

HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a technology for interconnection of computer processors. It is a bidirectional serial/parallel high-bandwidth, low-latency point-to-point link that was introduced on April 2, 2001.

HyperTransport - Wikipedia, the free encyclopedia

hyperthreading and hypertransport are 2 different technologies

HyperThreading is more hype than threading.
2 physical cores is way better than 1physical + 1 virtual core


and while hypertransport is way better that intel's quad pumped FSB..making the p4 eat dusk compared to A64s

but currently..intel's QPI ( of i7 |i5 | i3 ) is about 78% faster than the fastest amd hypertansport.
The HyperTransport Bus Used By AMD Processors | Hardware Secrets

The first version of the QuickPath Interconnect will work with a clock rate of 3.2 GHz transferring two data per clock cycle (a technique called DDR, Double Data Rate), making the bus to work as if it was using a 6.4 GHz clock rate (Intel uses the GT/s unit – which means giga transfers per second – to represent this). Since 16 bits are transmitted per time, we have a maximum theoretical transfer rate of 12.8 GB/s on each lane (6.4 GHz x 16 bits / . You will see some people saying that the QuickPath Interconnect has a maximum theoretical transfer rate of 25.6 GB/s because they simple multiply the transfer rate by two to cover the two datapaths. We don’t agree with this methodology. In brief, it is as if we said that a highway has a speed limit of 130 MPH just because there is a speed limit of 65 MPH in each direction. It makes no sense.
So compared to the front side bus QuickPath Interconnect transmits fewer bits per clock cycle but works at a far higher clock rate. Currently the fastest front side bus available on Intel processors is of 1,600 MHz (actually 400 MHz transferring four data per clock cycle, so QuickPath Interconnect works with a base clock eight times higher), meaning a maximum theoretical transfer rate of 12.8 GB/s, the same as QuickPath. QPI,

however, offers 12.8 GB/s on each direction, while a 1,600 MHz front side bus provides this bandwidth for both read and write operations – and both cannot be executed at the same time on the FSB, limitation not present on QPI. Also since the front side bus transfers both memory and I/O requests, there are always more data being transferred on this bus compared to QPI, which carries only I/O requests. So QPI will work “less busy” and thus having more bandwidth available.


QuickPath Interconnect is also faster than HyperTransport. The maximum transfer rate of HyperTransport technology is 10.4 GB/s (which is already slower than QuickPath Interconnect), but current Phenom processors use a lower transfer rate of 7.2 GB/s.

So Intel Core i7 CPU will have an external bus 78% faster than the one used on AMD Phenom processors. Other CPUs from AMD like Athlon (formerly known as Athlon 64) and Athlon X2 (formerly known as Athlon 64 X2) use an even lower transfer rate, 4 GB/s – QPI is 220% faster than that.
