Sapphire Vapor-X HD 5750 1GB GDDR5 Graphics Card Review


The Radeon 5000 series graphics cards were recently released by AMD / ATI. For the first time in several years, AMD / ATI (hereinafter referred to as AMD) is again at the top of the performance. NVIDEA will soon release its next generation of graphics cards, but no date has been set and very little information has been released to the press.

A few weeks ago, AMD released the graphics cards 5850 and 5870, which were very well received in reviews and by consumers. I did a review of an Asus 5850 card myself.

Just a few weeks later, AMD released the HD 5970, a dual GPU card codenamed "Hemlock", a very powerful and expensive card. You can check reviews on testseek.com for them. Here is AMD's current lineup:

I already discussed the news in my Asus HD 5850 review with the Radeon 5000 series, so I won't repeat everything again. Suffice it to say that the new generation has some new great qualities. First, the chips are manufactured using the new 40 nm technology, which promises lower power consumption and less heat. Second, the ATI EyeFinity technology enables the connection of up to three monitors to each card, which means a total of 6 monitors in CrossFireX. Other important features include support for ATI Stream (GPU acceleration), Open CL (API for processing in a parallel GPU CPU) and Directx 11.


OK, enough is enough; Let's take a look at the technical specifications of the Sapphire HD 5750 Vapor-X 1 GB DDR5:

On the box, Sapphire emphasizes Vapor-X technology and all of the new AMD technologies discussed above.

The card is secured in a box and enclosed in the usual antistatic plastic bag.

The supplied accessories are: a manual; a CD with drivers and utilities; the "ArcSoft SimHD" application; a voucher to download the Dirt2 game (supports DirectX 11); 2 Molex 6-pin PCIe adapter cables; a DVI-VGA adapter and a CrossFireX bridge.


The card itself looks really impressive with its massive cooling solution. I've had the opportunity to see models of the 5750 from some manufacturers, and the Sapphire card is ahead.

The cooling solution occupies a double slot, which can be a disadvantage as this card has to be classified as a medium range card and many users prefer cards with a slot in this segment. AMD / ATI sets the general rules by which manufacturers can build their cards, and they often leave small margins, which I think must be the reason why I haven't seen a 5750 single-slot card yet.

The technology used by the Vapor-X cooling system has its origins in the aerospace industry. The cooling liquid (in this case water) becomes steam on a hot surface (the GPU) and the resulting steam is condensed when it comes into contact with a colder surface, which converts the steam back into liquid and back onto the hot surface the process returns. Sapphire claims that the Vapor-X system is much more effective than the reference cooling system at up to 7 degrees.

In the right hands, less heat means less noise. This is another feature of the Vapor-X system.

To help the Vapor-X system cool the circulating fluid inside, Sapphire has installed an 80mm fan that is perfectly integrated into the black plastic cover. On one side of the plastic cover is the Sapphire logo, which glows blue when the system is running. Check out the picture below to see what I'm talking about.

This card contains the "Black Diamond" capacitors that have caused a stir in the industry. The aluminum polymer in these capacitors is superior to that used in "normal" aluminum capacitors. According to Sapphire, these capacitors are 25% more energy efficient than normal capacitors.

The card has an additional 6-pin PCIe power connector, as you can see in the picture below.

The 5750 Actual has two CrossFireX connections. However, due to the inefficiency of the Catalyst drivers, it is not recommended to install more than two cards.

The storage units are visible on the board of this card. There are four high quality Hynix GDDR5 chips.

There are four video outputs on this card, two standard DVI-I; an HDMI and a DisplayPort. This should satisfy the needs of even the most demanding users. The card is only 185 mm long and therefore fits in most cases.

Here are screenshots of my test system configuration:


Unfortunately, I received this card a little too late to test it on my old test system, on which I carried out many graphics card tests. This means I have to comment on the numbers without any real evidence of results from old tests. I will try to be as objective as possible.

It's no secret that AMDs cards in FutureMark benchmarking programs (3D Mark 06 and 3D Mark Vantage) often achieve surprisingly high scores. And this time was no exception, as you can see from the graphics above.

The DirectX 10 and Direct 11X Unigine tests were interesting for me because a few weeks ago I achieved results with the same tests on the Asus HD5850 card. One of the most important marketing points of the DirectX 11 is that it should be much faster than its predecessor. With the HD 5850, I got the opposite results, and as you can see from the graphics above, this also applies to the 5750 card. Obviously, AMD has problems here. Hopefully we will see improvements with the release of new Catalyst drivers.


The performance of the Radeon HD 5750 is spectacular. It is able to maintain a high FPS rate with all games in this first series. There was no problem when I improved the resolution and turned on filters. The fact that it contains 1 GB of GDDR5 with a bandwidth of 108 GB / s must ultimately help ensure that the games run smoothly even when the filters are switched on.


In the second battery of games, which contains the most demanding games, the limitations of the HD 5750 become clear. While it doesn't prevent us from enjoying the games overall, it's clear that this is a medium-range card. For HD 5750 you have to say that even the incredibly powerful HD 5850 had some problems with these games, in which all settings were set to max. If you consider that the HD 5850 has twice as many stream processors as the HD5750, you can rightly say that the HD 5750 is a very powerful card.


The release of the HD 5750 brings electricity to the mid-range segment. So far I haven't said much about overclocking skills, but reports from other reviews and forums have been positive. So I was really excited to test an HD 5750 card myself and see that the overclocking potential was really as good as I heard it. I can't deny that I got happier when I learned that I could test an HD 5750 with Vapor-X technology.

In fact, the overclocking capacity of this card is high. Check out the following screenshots I received without changing the tensions, but only with Catalyst Control Center.

After testing countless combinations, I got a stable configuration at 860 MHz for the GPU and 1345 MHz for the memories. This means an increase in the standard numbers of 23% for the GPU and 17% for the memories (percentages were calculated based on the values ​​for the reference model with 700 MHz for the GPU and 1150 MHz for the memories).

The Vapor-X cooling system obviously does a fantastic job. The following graphic shows the temperatures when the card is in idle and full load mode. The IDLE temperatures were measured after the system had been idle for half an hour. The FULL LOAD numbers were determined after the system had been under full load for half an hour (using Furmark 1.7). The room temperature was 17 ° C.

Vapor-X technology clearly does a lot to keep temperatures down. It's been a long time since I saw these low numbers at full load. I will say it again; The Vapor-X does a great job.

The noise level is always difficult to discuss because it is very subjective. The fan can be set manually or automatically. During my overclocking the fan was set to self-regulation and turned at 50% of the maximum speed. I think the sound it made on these levels is perfectly fine, but if it goes beyond that, it becomes noticeable and a bit annoying.
