Core 2 Q9300 or Q9450 Which one is better How big is the gap Kneel down and beg the master!!!!!

The difference between the two is not big, only %5 is the difference and both are high-end processors.

It's better to buy this CPU than to buy i3, which has a large heat, low efficiency, old platform, and old architecture.

Core Q94002010. Core Q9400, the interface is LGA775, its main frequency is, the external frequency is 333MHz, and the frequency doubling is 8. It has a 1333MHz front-side bus, up to 6MB of L2 cache, and 05A compliant power supply.

Product performance. The Q9400 has a core voltage of 45.6 billion transistors and a core area of 164, supports virus protection technology, supports enhanced Intel Speedstep technology, supports enhanced pause state (C1E function), supports Intel 64 technology, and its operating temperature can reach up to Celsius.

Intel Core 2 quad-core Q9400 processor with 45nm process, front-side bus 1333MHz, L2 cache 6MB, and thermal design power consumption of 95W, which is equivalent to half of Q9450 L2 cache. S-SPEC designation SLB6B. The core type is Yorkfield, and the interface type is LGA775 process technology.

The CPU supports instruction sets MMX, SSE, SSE2, SSE3, SSE3, and EM64T. There is an original fan in the box.

Q8300: This U is cost-effective, when it was first listed**only half of Q9550,But the performance must be about 75% of Q9550,Many high-end machines in 2008 choose Q8300,The only drawback is**The decline is too slow,Now it's still more than 800 yuan,AMD's X4 640 are below 700!

Q9550: The most famous one of all 12MB L2 models, the overclocking performance is generally good, especially the E0 stepper batch, which is basically 4GHz, which is very scary. It's a pity that the house rules are too expensive, and the current ** is still as expensive as the i5 750, which breaks the hearts of most LGA775 veteran players.

Q9300 said: A very"That"of the model. That is to say, it is really not cost-effective,L2The capacity was cut from the native 12MB to 6MB at once,Of course6MB is also very good,But**It should be lower than 1000 yuan,It's a pity that it has never been lower than 1000 yuan since it was listed,It's better to choose Q9550。

There are not many advantages of this U, and the power consumption control is better.

Q9600: I really don't know this model, it's nothing more than Q9550 The frequency is called a little bit higher"q9600"That's it, nothing special.

Q9700: The situation is similar to Q9600, but ** is exactly the same as Q9600. Considering the overclockability of the Q9550, I don't think it's necessary to consider this model, if the Q9550 is not satisfied, then you can actually choose the QX9650, but you have to consider the overhead.

i3 530: A model that is very speechless, its only advantage is that the single-task performance is still at the same level as the e8400, as for multitasking, there is no advantage in dual-core and four-thread, not as fast as the physical 4-core X4 640, and some games need to turn off hyper-threading technology, otherwise the game will be abnormal, this is definitely a failure. At present, the i3 530** has dropped significantly, but the original price is not very expensive, and it has been topped by the slightly higher frequency i3 540.

Among these U, the old U King I think of course is Q9550, Q9600 and Q9700, and the enhanced core2 architecture and 12MB of super large L2 make them worthy of it"u king"location. For LGA775 models (5 U except for the i3 530), it is recommended to choose a motherboard such as X38 or P45, such as the Gigabyte EP45-UD3R, which is good, and the Q9550 should be able to easily get on 4GHz with this board.

i3 530 with ASUS P7H55-M Forget it, ** is not expensive, and the warranty is 3 years also assured.

Due to these two processor architectures.

The same and the same frequency, so the performance of a single core is basically the same.

It's just that the Q9400 has more cores, so the multi-core performance is 113% higher than that of the E5400.

Hello, there is no CPU Q9400, only i5 9400.

The performance gap is still very large, 9400 belongs to the mid-to-high-end CPU is slightly lower, and 4590 belongs to the low-end CPU is on the upper side, and the performance gap between the two is very large.

In addition, the 9400 is the ninth-generation Core, which is the current mainstream CPU, and the power consumption, process, and design are all advanced, while the 4590 is an old product five years ago and is relatively backward.
