Introduction:

The AMD Radeon R9 295X2 is the best reference launched Dual GPU'd card in terms of raw performance currently on the market. Housing two of AMD's flagship R9 290X series GPU's which are slightly underpowered makes this card a solid option for any top enthusiast. The 295X2 reference design comes available with a pre-installed water cooling system by asetek, the advantage of this is it keeps the card much cooler, as the R9 290X is a very hot running card with it's reference designed cooler. With a TDP at 500W it's no doubt that water cooling the card was a sensible choice to make. The drawback however is that this particular cooler is very loud, averaging around 46.5 dbA. Holding 8GB of GDDR5 memory makes this card most certainly seem appealing, however when in crossfire it only uses 4GB of GDDR5 memory, as in crossfire memory is not added but mirrored. This card has a core clock at 1018 MHz and a memory clock at 5000Mhz, this is a first seen by any of us, as most of the time dual GPU'd graphics cards are seriously underclocked but this card is only limited by around 80W, whereas the Titan-Z is underpowered by 125W for two Titan Blacks which each at total TDP is 250W. You would expect the higher the power consumption of the card the higher the value of the power limitation compared to other cards which draw less power. The R9 295X2's GPU's are actually factory overclocked by 18MHz compared to the R9 290X's 1000Mhz base speed, this as a first look is very impressive as cards such as the GTX 690/Titan-Z are underclocked by more then 90MHz. This makes the idea of a Dual GPU'd card very appealing, and after the price cuts maneuvered by the manufacturers, a solid route to take. The card itself is on the enthusiast end of the scale, and is currenty the second most powerful graphics card available on the market today (ROG ARES III is the first). The cards relative and overclocked performance will be listed later down in the thread. The below lists all of the current R9 295X2 models available and their in-detail specifications;

Note: All specifications are taken under the following conditions:

-idle/load fan noise are with AUTO fan control settings

-idle/load temperatures are taken with STOCK MANUFACTURER clock settings. Cards can and will have varying clock and memory speeds per varying model.

-ALL Power supply requirements are from the manufacturer directly, These are not my recommendation.

-ALL Max power consumption Wattage's listed are from it's Power connectors + motherboard power output. The value given is the combined Absolute max power draw and does NOT mean it will get to that figure even when under max load. 8-pin connectors can achieve 220W and 6-pin 110W, all modern power supplies can handle and output this amount, with the motherboard outputting 75W per PCI-E slot.

-ALL memory clocks are given as an effective value.

-Only cards longer than 300mm are given a drawback warning to check case dimensions, ALWAYS check to see that a card fits in your case before purchasing any card.

-Average temperature/fan noise values taken is the halfway difference between the load and idle numbers presented.
