Leadtek winFast PX7900GS-7950GT TDH extreme review-benchmark



 Do You know what Extreme is? This always something extraordinary. And Leadtek precisely calls its accelerators series, which work at the high frequencies.

We will today we will review two video card from this company, which do not relate to the most rapid class, but at the same time they relate to most popular group from the Middle- segment.

These are GeForce 7900 GS and 7950GT. The first differ from the second in terms of pipeline and frequency . in the first some are blocked (in more detail it is possible to see the specifications of cards below). leadtek company decided to reduce the cost of 7950GT, after equipping it with only 256- megas-byte  memory, when as all regular such card is proposed with complete 512- megas-byte. But  user could not feel a large impact in the perfomance since the frequencies of card was raised from regular 550/1400 to 600/1430 MHz. Thus, in games, where the greatest requirements are imposed by shader calculations, this card will demonstrate higher performance, despite the smaller memory volume .

As far as 7900GS are concerned, the version from leadtek is also overclocked (520/1400 MHz against regular 450/1320 MHz). Both video card although relate already to the previous family g71, but not to G80; however, on the market for present games they both ensure practically all contemporary functions. The only function witch is not available is the operation HDR+AA .

The card 7900gs and 7950gt extreme

Memory used

Memory used

Video Cards has 256 MB memory GDDR3 SDRAM, placed in the front side PCB.

Memory Microcircuits are from hynix (GDDR3). Access time in the memory microcircuits is 1.4ns, which corresponds to the frequency of 700 (1400) MHz.

Comparison with standard design, front view

7900gs standard design

Reference card NVIDIA geForce 7900 GS

As u see, before us the universal solution.

Both card are made on the base for the simplest seen by us PCB with memory system bus  256 bits as in 7900GT. This last, appeared almost a year ago, and was the cheap relative to the  Hi-End 7900gtx, and now also it serves in the Middle- sector.

Connection to the analog monitors with d -Sub (VGA) is produced through the special adapter- adapters DVI-to- d -Sub.

Maximum resolutions and frequency:

  • 240 Hz max refresh rate
  • 2048 x 1536 x 32bit x85Hz max - on analog interface
  • 2560 x 1600 @ 60Hz max - on digital interface

About the possibilities of video card on the playback of MPEG2 (DVD-Video) , Depending on film the CPU load with the playback on all contemporary video cards does not rise above 25%.  

Now about the cooling systems. Both card (Leadtek winFast PX7900GS TDH extreme (GeForce 7900 GS) 256MB PCI- E  and Leadtek winFast PX7950GT TDH extreme (GeForce 7950 GT) 256MB PCI- E) possess the same cooler.

This the good old large radiator, which covers the core and memory microcircuits. That fan force the cool air to pass though turbine which is located above the die and memory. Fan rotation speed is low; therefore it is practically noiseless.

The use of 600 MHz on core is not good point for 7950gt since even the enormous powerful cooler from 7900 GTX has not easily managed this heat emission, then here it clear that the cooler installed on the 7950gt extreme is not sufficient, any way the core temperature  did not exceed 80 degrees.

Inside the box.

Delivery set in both card is identical. user Management , disk with drivers, game serious sam II, SpellForce2, disk with P.O. Cyberlink\'s collection for the creation and playback DVD, adapters DVI-to- d -Sub and S -Video-to-RCA, fan external power connector

Conclusions

Leadtek winFast PX7900GS TDH extreme (GeForce 7900 GS) 256MB PCI- E - Good selection for the level of 180-210 US dollars, high frequencies give this card already a good boost. Good delivery set with contemporary game . I repeat, that if the card price will be lower than RADEON x1950 PRO. it is possible to say that this is a a good selection,

Leadtek winFast PX7950GT TDH extreme (GeForce 7950 GT) 256MB PCI- E - This card is completely original. The question here : what is better - high frequencies and small memory volume or large memory and low clock frequency? I assume that for overclocker it is better to go with more memory, the frequency can be raised. But for simple user this became a bit difficult .For the same price u will obtain card on the level Of x1900 XT.

Both products according to tradition have excellent quality.
