AMD Radeon HD 7970 3 GB

Introduction

Out with the previous, in with the new. Let's welcome the latest child on the block, the Radeon HD 7970, a part of AMD's bright Southern Islands GPU family. This card is that the industry's 1st with a number of things, it uses {the 1st|the primary} ever high-performance GPU designed on the twenty eight nanometer silicon fabrication process; Radeon HD 7970 is that the industry's first card compliant with Microsoft's DirectX eleven.1 API, which is able to ship with future major version of Windows; and is that the 1st card to use the PCI categorical three.0 x16 bus, that doubles system interface bandwidth to thirty two Gb/s and is touted by motherboard makers because the next massive factor since PCI.

New generations of GPUs naturally bring with them performance increments, some times even 100 percent that of preceding generations, they additionally function launch-vehicles for brand new options that quickly endure to become trade standards, and facilitate the technology grow. The Radeon HD 7970 has each of those responsibilities resting on its shoulders: to attain performance wins, and pack some killer new options that matter to the end-user.

Product Positioning

The AMD Radeon HD 7970 could be a distinctive card from a market-positioning standpoint. when Radeon HD 2900 series, and therefore the completion of ATI's merger with AMD, the corporate took up a singular model of product development that ensured it might have competitive merchandise out within the market targeting each phase, whereas not having to pay a lot of on creating giant GPUs. Its goal with a brand new GPU design perpetually concerned creating a killer high-performance (not high-end) GPU, and using it each ways: in dual-GPU cards as high-end merchandise, and by disabling some components/features to carve out cheaper/cost-effective merchandise.
The AMD Radeon HD 7970, notably the GPU behind it, codenamed "Tahiti", is stretching that model a trifle towards the higher-end. Tahiti is larger than what AMD's typical "high-performance" GPU is meant to be. For one, it options a 384-bit wide memory interface. AMD was the primary to promote with GDDR5 memory commonplace, that it initially sought as how to avoid the requirement for a GDDR3/4 memory bus wider than 256-bits. With NVIDIA catching up with the memory commonplace, and implementing a 384-bit GDDR5 memory interface on its GeForce Fermi 100/110 GPUs, AMD felt the pinch for doing one thing to extend the memory bandwidth of the HD 7970, to stay up with the increasing compute performance of their GPUs. the corporate selected slightly faster GDDR5 memory chips with HD 6900 series, however it might solely yield little bandwidth gains. the sole choice left while not having to change memory design to the lesser known XDR2, was to extend the memory bus width physically by five hundredth, hence 384-bit. in addition to the faster five.5 GT/s memory chips it used on the HD 6900, and applicable clock speeds, it yields around 260 GB/s of memory bandwidth.

Game

The latest addition to the Collin McRae Rally franchise, DiRT 3, of multi-format rally motorsport. DiRT three introduced additional of a similar nice racing expertise Collin McRae DiRT two gave you, however with higher gameplay, and therefore the new Gymkhana freestyle motor-acrobatics mode, that you will additional probably love than hate. It uses a additional polished, performance-optimized version of the EGO engine, version 2.0, that takes advantage of additional DirectX eleven options than version one.0 used on Collin McRae DiRT two, did.

Crysis a pair of takes the player into an alien-infested the big apple town. the sport adds a tactical choices mode that enables many approaches to attack a heavily infested enemy location. The new Nanosuit a pair of.0 that the player uses offers a lot of freedom in ability use, as an example multiple skills will be used at a similar time. to raised accomodate a given play vogue weapons will be customized with silencers, laser sights or perhaps a sniping scope.

For rendering Crytek's CryEngine three is employed that comes with reduced system necessities compared to the primary Crysis game. Since Crysis a pair of may be a multi-platform game, with major development specialize in console, the graphics on launch day were solely DirectX nine. DirectX eleven functionality was added later in an exceedingly patch. we tend to use the DX11 version and therefore the high-res texture pack for our benchmarking.

Call of Duty four may be a first-person shooter that's designed on the award winning decision of Duty Series. it's the primary version to play in trendy times. in a very near-future conflict between the us, Europe and Russia you get to play as a us Marine and a British SAS operative. The engine is Infinity Ward's own creation and has true dynamic lighting, depth of field, dynamic shadows and HDR. even if the sport plot is scripted you may end up in intense battles, typically operating at the side of laptop controlled team mates. Later installments of the decision of Duty Series use identical game engine, thus this check is additionally representative of decision of Duty: trendy Warfare three performance.

Arguably the foremost anticipated on-line shooter title among real gamers - computer gamers, Battlefield three is that the latest addition to a number of the foremost participating on-line multi-player shooter franchises. It combines infantry combat with mechanized warfare together with transport vehicles, armored personnel carriers, main battle tanks, attack helicopters, combat aircraft, just about everything that goes into today's battlefields. The infantry combat is including role-playing parts, that makes the expertise all the additional participating. It conjointly incorporates a single-player campaign that added some gigabytes to its installer.
Behind all this is often a clean game engine by EA-DICE, Frostbite two. It makes use of each attainable feature DirectX eleven must provide, together with hardware tessellation, and new lighting effects, to deliver a number of the foremost fascinating visuals gamers ever had access to. Not taking part in this game on computer is grave injustice to what is in store. Faster PCs are rewarded with higher visuals.

Batman is back on the LCD screen with Arkham town, a sequel to Batman: Arkham Asylum, by Rocksteady Games and WB. it absolutely was released to the computer platform in November. Batman is imprisoned in Arkham town, an infamous district of the DC Universe that contains the scum of Gotham, most of that Batman helped get in there. so as to urge out he should bear immeasurable baddies, and encounter several of the enduring super-villains along the means. he isn't entirely alone.
Batman Arkham town uses a similar Unreal Engine by Epic, as Arkham Asylum, however because of the engine's modularity, it's been overhauled, outfitted with the newest technologies, together with a graphics engine that takes advantage of DirectX eleven.
