RRR3 video memory 1G or DDR5 video memory 512 Okay, I m playing games

DDR5 memory 512 is good.

The display is at 22"(1920x1080) below 1G and 512MB The gap is less than 1%...However, DDR3 is much worse than DDR5.

The key is bit width.

For example, the bit width of DDR3 is 128, and the bit width of DDR5 is 64, then the performance of DDR3 is good, and DDR5 is limited even if it is fast, just like the little fish in the bathtub!

Therefore, you can't just look at the model when buying a graphics card, but also look at the performance, if DDR5, the bit width is 256, then the performance is folded to the high-end, and the graphics card display chip should be valued, A card should be selected HD6750 HD6770, etc., and N card should be selected GT9800 GT430 GT440, etc., all of which are mid-to-high-end.

Watch what game, DDR5 will be faster.

DDR5 is much better than DDR3 and is not a level.

It depends on the type of graphics card and the resolution you want to use.

DDR3 video memory 1G is better. In contrast, the interface will be displayed more clearly.

The specific differences between DDR5 and DDR3:

1. Different speeds - GDDR5 frequency can reach more than 2 times faster than GDDR3.

2. Lower power consumption - GDDR5 is 20% more energy-efficient than GDDR3

3. Higher bandwidth - GDDR5 with 128bit video memory is still faster than GDDR3 with 256bit.

When choosing a graphics card, it is not as important as the memory or the frequency of the graphics card, and the reasonable combination of the two is the best performance of the graphics card. Because the performance of the graphics card is determined by the core frequency, stream processor unit, video memory frequency, video memory bit width, etc., so in the case of different display cores, high core frequency does not mean that the graphics card has strong performance.

For example, the core frequency of the GTS250 reaches 750MHz, which is higher than the 576MHz of the GTX260+, but the GTX260+ is definitely stronger than the GTS250 in terms of performance.

DDR5 and DDR3 refer to GDDR5 and GDDR3 respectively, and their differences:

1. Speed. GDDR5 frequencies can reach more than 2 times faster than GDDR3.

Data prefetch is twice the amount of data prefetched by GDDR3 and the DQ parallel bus, doubling the actual speed of GDDR5 memory. Not only that, the GDDR5 memory also uses the DQ parallel dual bus, which is equivalent to providing an additional channel on the original basis, while the previous GDDR3 memory only has one channel.

2. Power consumption. GDDR5 is 20% more energy efficient than GDDR3.

The working voltage of GDDR3 memory particles is only the GDDR5 memory voltage, and it also has excellent power management technology, so the power consumption is naturally lower. Not only that, GDDR3 mostly uses 80nm process, while GDDR5 is 55nm, and the improvement of the process greatly reduces the size of the chip and the heat can be much lower.

3. Bandwidth. GDDR5 with 128-bit video memory is still faster than GDDR3 with 256-bit.

With the same chip, the GDDR5 version of GT240 will be faster than the GDDR3 version, and when the frequency is further increased (650 4000MHz), the gap between the two will be pulled to 38%. At this time, the GDDR5 version of the high-frequency GT240 is 24% higher in performance than the 256-bit 96GT, and even close to the 98GT with higher chip performance.

4、**。The market price of GDDR5 is significantly higher than that of GDDR3.

"DDR5 technically doubles the frequency of DDR3. "—Actually, it's not doubled, it's almost 10% great.

Bandwidth determines performance. Bandwidth = Frequency * Bit Width. Add the unit conversion to 8 1000.

For example, on the highway, the frequency is the speed, and the width is the lane. That's where memory dual channels come in. Double the bit width, and the performance is naturally doubled.

This has nothing to do with dual channels, the bit width and high performance are good, but it is not doubled either.

1g. Video memory if the actual frequency is the same.。。 And the width of the bit is 128. The bigger the worse a third. "I don't know.

In short, the graphics card looks at the bit width, the frequency, and the memory size and type (DDR5 or DDR3). "The most important thing depends on the GPU type of the graphics card, just like the GT250 and GTX460, the former bit width, frequency, and video memory are 10 times higher, and it is useless.

DDR5 doubles the interface bandwidth, new technology, nothing else
