AMD’s New 380x

In performance terms, there is a huge difference between the midrange and high end graphics cards out there. There is room in the marketplace for an ‘inbetweener’ – a priced starter that could sit at the GBP200/$230 place in the industry. AMD has got with the R9 380X and itis a merchandise that was fascinating.

In effect, it is an unlocked variant of the present R9 380, predicated on the Antigua central processing unit when it debuted in 2014’s Radeon R9 285 formerly called Tonga. Texture units also find a rise from 112 to 128. In theory at least, that is an added 15 per cent of central processing unit power assuming like-for-like clocks.

The card also sends with 4GB of GDDR5 RAM as standard, with no 2GB choice. Memory consumption in gaming is just moving in a single direction, along with the R9 380 in particular has fought in some specific names. At 1440p and both 1080p, 4GB of video RAM has not proved insufficient in including nearly every game we have examined at max settings thus far. Yet, looking at processor photography of the Antigua processor, there’s evidence to indicate that it’s a 384-bit memory bus, indicating it may have been initially designed for 3GB/6GB settings.

The card we are testing here is something of a stone. It is a beautifully designed card, Sapphire’s Radeon R9 380X Nitro. Build quality is outstanding – itis a strong building using a brushed finish backplate, silent operation, and a quality fans. Inputs and outputs are normal – there are double DVIs (one with analogue support), DisplayPort and HDMI 1.4. Electricity is provided via two six-pin PCIe input signals.

Sapphire’s assurance in its building here extends to a factory overclock that is pretty meaty. In addition to that, our review sample is the most overclockable Tonga/Antigua-based card we have had in for testing. It needed us raising fan speed, but we reach 1150MHz on the heart with 6.5gbps of memory bandwidth. This really is fairly remarkable.

And our guidance is the fact that in the event that you are going to get a Radeon R9 380X, obtaining a version as great as this one is an excellent idea – because as you will notice from the standards under, the the truth is the fact that the card is not really that much quicker than the present R9 380 running at stock frequencies, even with the meaty factory overclock in place.

Our evaluations start by far the most famous gaming resolution – at 1080p resolution, as stated by the top goal for the R9 380X’s abilities, as well as the Steam hardware survey. Up against the Gigabyte GTX 960 4GB we examined, the 380X reveals a considerable development – even managing to post progress above the 20 per cent threshold in really demanding Assassin’s Creed Unity and names like Crysis 3. Battlefield 4 – a game that Nvidia spent lots of resource plus time optimising – finds a nine per cent improvement on the R9 380X.

The boost is less pronounced in comparison with the present R9 380 coming in at around 10 per cent usually, though specific names can find that expand to a creditable 15 per cent. That is not bad, but it is not the midway measure between the R9 380 and R9 390 that many may have expected for with this merchandise, and that is with an adequate factory overclock set up.

Happily, there’s farther overclocking headroom accessible.

Much is made of Nvidia‘s second-gen Maxwell and its own capability to overclock to comparatively extreme frequencies. The 4GB GTX 960 we examined or so the inquiry is to what extend shoving it close to the limitation sits at 1450MHz increase can assist in making the card that is slower competitive. The response is that Nvidia’s merchandise is still bested by an overclocked R9 380X. Clearly, individual card results may fluctuate based on overclocking results, but in our evaluations, we found a 19.5 per cent progress in AMD‘s favour.

Performance leadership here drops down to 13 per cent when compared with the stock R9 380 – and remember the Sapphire card examined here does attributes a factory overclock.

We analyze peak power consumption – and overclock equilibrium – by using a unique, repeatable scene located at the ending of the Welcome to the Jungle period, pictured below of Crysis 3. The mix of generous lashings of alpha effects and elevated rates of geometry causes a spike to power consumption we just can not duplicate elsewhere. We keep the Center i7 4790K used elsewhere in our evaluations, to be able to eliminate any possible spikes in power consumption due to a CPU overclock, but we dial it down back to stock frequencies.

And at this stage, why the R9 380X posts critical functionality improvements over the Nvidia GTX 960 cards we have tested, it is quite clear – it is drawing on 35 per cent more electricity at peak load. But that is really a reasonably great commerce when it comes to performance per watt contemplating the degree of the higher frame rates the new AMD card is supplying, especially at 1440p. The added shaders plus the memory overclock incurs an added 27W load in comparison with a conventional R9 380. Not bad.

The main point is the fact that paired with i7 or an overclocked mainstream Center i5, a quality 500W power supply should readily have the capacity to handle a totally overclocked system shoved as far as it can. The R9 380X is more thirsty in relation to the contest, but the increase to functionality makes it a cost worth paying.
