This card is really quiet. It is said to be an intelligent speed regulating fan.
Starting with its parameters, we compare the graphics card to a main road. The more cars we can drive at the same time, the better the graphics card!
The type of memory is the quality of the road. The flatter the road, the faster the speed! Low-level memory is like a muddy road with potholes, which affects speed! Now the mainstream video memory type is GDDR3, and the high-end graphics card has already used GDDR5. This graphics card belongs to the mainstream memory type, OK.
The core frequency is like the traffic police on the road. A traffic policeman with a dull mind often can't command the traffic well, and the traffic jam is serious, so the speed is naturally slow! The core frequency is equivalent to the CPU in the graphics card, which we call GPU. The higher the GPU, the better. Mainstream graphics card 600MHz+, this graphics card 325MHz, general. This parameter has little effect.
Memory frequency is like a speed limit sign on the road. The general highway speed limit is 80km, and the good expressway speed limit is120km. Expressway's speed, of course! The frequency of video memory is equivalent to the memory in the graphics card. The higher the frequency, the better! Mainstream graphics card 1400MHz, this graphics card 1580MHz, OK.
The memory bit width is equivalent to the width of the road, and the road with 10 lane is always smoother than the road with 4 lanes! The larger the memory bit width, the better. The mainstream graphics card should be 256bit. This graphics card is 128bit, which is a bit low. I'm afraid this will have a great impact.
It's useless to say it, mainly depending on the actual performance of this card. I installed several pieces for my client, and tested the graphics card with 3DMARK06, and scored 8000+, which is a good graphics card. (The mainstream 9800GT generally scores 10000+, and of course the price is more expensive. )
2. All 3D games made at this stage can run normally. I have a guest named devil may cry 4 who took the best picture. The picture is dazzling. As for StarCraft 2, Crysis, Assassin's Creed 2 is unfamiliar, and normal operation is definitely no problem.
3, this question is not absolute, this mainly depends on the comprehensive parameters. I have explained the first point above in detail. Choosing a graphics card will teach you the simplest and most effective way. Ask the seller directly what score this graphics card scored in 3DMARK06. Generally, dual-core CPU reaches 8000+ mainstream.
