I heard that the N graphics card 6800Ultra is stronger than the 7300GT, how much stronger? Is there

Says who? Why don't you say that the 8800GT is stronger than the 9800GTX

Due to the gap in architecture, although the 6800Ultra has strong parameters, its performance is basically equivalent to that of the 7600GT, which is a notch stronger than the 7300GT.

As for the 8800GT, it is definitely not as strong as the 9800GTX, the gap between 112 stream processors and 128 stream processors is still the gap in frequency.

It should be ... That's right..

6800 is the high-end of the 6 series.

The 7300 is the 7 Series low-end...

Although cross-generational, it is definitely still 6800 strong. Didn't you hear the story of Tian Ji horse racing when you were a child? . .

The first floor said. Why don't you say that 8800GT is stronger than 9800GTX...

I say.. 8800 is certainly not as strong as 9800. But 8800 is definitely stronger than 9300...

The 6800 Ultra has about the same performance as the 7300GT, with the 7300GT being a little better than the 6800 Ultra by a negligible margin. The scores of the 3DMark 03 on both graphics cards at 1027*768 resolution are around 11000, and 05 is around 5000. In fact, it can be said that it is comparable.

Yes, for example, GF7900GS is stronger than GF8400GS, 20%, but the power consumption and heat generation are much higher, which is not cost-effective.

The performance of GTX650 is comparable, and the parameters of the two are:

1. HD7700 graphics card parameters:

Type of product: Graphics card.

Brand: AMD

The model of the chip: AmdradeonHD7770 The capacity of the video memory: 1024M

Type of video memory: GDDR5

Frequency of the core: 1000MHz

Frequency of video memory: 4500MHz

Unified architecture: 640.

2. GTX650 graphics card parameters:

Type of graphics card: Mainstream.

Graphics chip: GeForce GTX650

Core frequency: 1058 1110MHz

Frequency of video memory: 5000MHz

The capacity of the video memory: 1024MB

Bit width of video memory: 128 bits

The differences are significant, and the differences are in these areas.

1. The video memory speed is different.

1. HD 7730M: The memory bit width is 128bit, and the memory speed is .

2. GeForce GTX 660M: 128-bit memory bandwidth, 80GB s.

Second, the memory capacity is different.

1. HD 7730M: memory type DDR5, video memory capacity is 1024M.

2. GeForce GTX 660M: Memory type DDR5, video memory capacity is 2048M.

Third, the core frequency is different.

1. HD 7730M: The core frequency is 900MHz, and the memory frequency is 4500MHz.

2. GeForce GTX 660M: Core frequency: 835 1250MHz.

Compared with the two notebook graphics cards, the GTX660M wins, and its performance exceeds the HD7730M many times.

1. The performance of the GTX660M graphics card is slightly higher than that of the desktop independent graphics GTS450, which is lower than the GTX550TI. Compared to the previous generation, the performance is between 560m< 660m < 570m. It is a mid-range slightly lower-level graphics card, and it is full high to play Battlefield 3;

2. HD7730M graphics card performance, which is an entry-level product, and its performance is lower than that of Intel CPU core HD2500.

The HD7000 is a series, not a discrete graphics card. Among the discrete retail graphics cards currently on the market, the lowest end of the HD7000 is the HD7750, and the highest-end is the HD7990, even so, the lowest-end HD7750 performance in the HD7000 series is a notch better than the GT730 performance.

And 730 is a scum, and you will definitely regret buying it.

HD7000 is a series, please name the specific model.
