No. It is much more powerful.
The Intel Pentium DualCore 1.43Ghz is the Merom T2310 with 533fsb, 1MB L2 Cache, 65nm, and the unnamed 2.5Ghz could only be the Intel Core2Duo Penryn T9300 with 800fsb, 6MB L2 Cache, 45nm. The Penryn is newer, faster and more efficient.
No. The Pentium M is an older, 32-bit only processor. The Pentium Dual-Core is faster and supports 64-bit operation.
No. It is far more efficient. Essentially, it is a cost-reduced version of the Core 2 Duo, but it is still more powerful than any Pentium 4.
The AMD K6-III and early Athlon processors are roughly equivalent in speed and performance. Via C7 processors, although released much later, are close in terms of performance to a Pentium III.
The Intel Pentium II was released in a Slot 1 package, while the Pentium Pro used socket 8. Adapters were available to use Pentium Pros in Slot 1 motherboards, and a version of the Pentium II was released for Socket 8.The Intel Pentium II includes MMX instructions, while the Pentium Pro does not.The Intel Pentium II has improved performance in 16-bit applications. 32-bit applications were not affected quite as much.
I would choose the Athlon 64 x2 over the Pentium dual core. They are fairly equal for most tasks yet the Athlon x2 is cheaper. I feel that I'm only paying for the name with Intel.
The difference is in P4 the new technology "Hyper Threading" has been implemented, the number of pins has been increased and cache memory has been increased. ~ Pentium III is an 80686. Pentium 4 is an 80786. For Pentium 4, you have to find programs that are compiled for the Pentium 4 or else the performance will be low. All Intel processors use the ISA instruction set developed back in the early 80s. First it was an 8-bit instruction set. Then there was the 16-bit. Next came the 32-bit instruction set, and the processors since the 80386 use it. Each processor model designates with the 80x86 notation. Each model increase in features and sometimes performance. Now the x86 computer industry is advancing towards the 64-bit instruction set. 8086 = 8-bit, 80186 = 8-bit, 80286 = 16-bit, 80386 = 32-bit, 80486 = 32-bit, 80586 = 32-bit = Pentium, Pentium MMX, K5, K6, K6-II, K6-III 80686 = 32-bit = Pentium Pro, Pentium II, Pentium III, Athlon, Athlon XP, Opteron*, Athlon FX-51*, Athlon FX-53*, Athlon 64* 80786 = 32-bit = Pentium 4 * = 32-bit/64-bit If you have compiled a program for 686 architectures, only the processors equal to it or above it can execute it. If you have compiled a program with MMX/SSE/3DNOW instructions, processors that have it will be optimized and processors that do not have those instructions will not be optimized. ~ Speed.

No. The Celeron is much slower.
no its not
This depends on whether you are comparing AMD or Intel processors. You CANNOT use ghz to compare processors anymore because it is inaccurate. AMD currently uses the names ( in order from weakest to strongest) E2, A4, A6, A8, A10, FX4xxx, FX6xxx, and FX8xxx (higher number are better for the FX). Intel uses Atom, Celeron, Pentium, i3, i5, and i7. Intel is usually faster than AMD processors but it will only matter if you need high performance. The Pentium is about equal to A6, i3 comparable to the fx4xxx, and the i5 is comparable to the fx6xxx. The i7 is usually a faster choice than the fx8xxx but is more expensive
