Core 2 Duo or Dual CoreThe Core 2 Duo is Intel's second generation (Hence, Core 2) processor made for desktops and laptops designed from the ground up to be fast while not consuming nearly as much power as previous CPUs, Dual core is simply a generic term referring to any processor package with two physical CPUs in one. Dual Core is better because it has 2 processors. The more the better. (Dell has a Quad Core, 4, processor computer and Mac has a Dual Quad Core processor, yes 8 processors). The main difference is that core duo is 32-bit processor, where as Core 2 Duo is 64-it processor, also for Core 2 Duo, the cache memory is 4MB compared to 2MB of Core Duo.--------------------------------------------------------------Samkad -Lets try to make it clear -Dual core and Core2 Duo both use 2 cores to process instructions..... good.... ok... but what's the difference then...Well... the main difference is in the cache memory they use.....The Dual Core processors use single cache shared between the 2 cores... plus, the size of this cache memory is usually less as compared to Core2 Duo ones (typically in size of 128 KB to around 512 Kb or 1 MB)......On the other side Core 2 Duo processors also use 2 cores but they have dedicated cache memory assigned to each of the core. so in effect there are two cache memories (note - in case if you don't know what exactly cache memory is - its a static memory - Static RAM - which is costly - and charged per KB size - because they are embedded into your processors.... and your processor stores instruction set into these cores and also info of frequently accessed memory locations so that it doesn't need to go to your main memory - RAM - on motherboard - every time and search indexes to get these locations. The result is - your access time is greatly reduced.. ok.. enough of info... lets get back to main topic)... so, the more cache your processor has got, the more costly will it be and more info can it store and faster will it become.... coming back to Core 2 Duo processors.... the cache size is typically 1 MB to up to 4 / 6 / 8 /12 Mb of size. so if a core 2 duo processor config states 4 Mb of cache, then effectively your 2 cores will use 2 Mb each... now you can make out the difference in speed between a dual core using 512 cache and a Core 2 Duo using 4 Mb of cache... and the same reason why core 2 duo processors are costly and more faster (about 40 %) than the dual core ones...Finally... to summarize, dual core procs (less cache size and that too shared cache between two cores) are strip in version of Core 2 Duo procs (more cache size and independent cache between each of the two cores), which make Core 2 Duo procs costlier and faster than Dual Core procs... so the winner is Core 2 Duo (and its comes with a price...)hope everyone is clear now....lets make it simple............cheers,Samkad
T6500 is faster and also, the T6500 is not "core duo" like the T4200 but "Core 2 Duo" (newer)
FSB, frequency, and cache size.
Core 2 Duo is FASTER. Pentium M is based on OLD technology and run on a SINGLE PROCESSING CORE whereas the CORE 2 DUO has 2 PROCESSING CORES. It has higher CLOCK SPEED, FSB, CACHE. Simple!
Of course Core i7 860. It's 4-cores, 8-threads processor while Core 2 Duo is only 2-cores, 2-threads. Moreover i7 860 got 8mb of Intel smart cache memory.
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
Duo Core consists of two cores on one die, a 2 MB L2 cache shared by both cores, and an arbiter bus that controls both L2 cache and the front-side bus access. Quad core is a processor with four cores on one die.
The Pentium Dual Core has a smaller L2 cache than a Core 2 Duo. It essentially fills the same role as the older Celeron processors; a cost-reduced version of a more powerful chip.
Very little, actually. The Pentium Dual-Core has a smaller L2 cache, making it just slightly slower than a Core 2 Duo at the same clock speed.
Core 2 duo is dual core. And before that was core duo which was dual core too...
core 2 duo will be better.
