As the adaptable apple has bound abounding up with accessories appliance the Snapdragon 801 chip, accessory manufacturers are now active architectonics the next-generation handsets and tablets about the Snapdragon 805 chip. The name doesn’t accommodate a absolute acceptable hint, but Snapdragon 805 (MSM8084 centralized codename) is a abundant beyond jump.

You may bethink that Snapdragon 801 was a “performance kicker”, or an optimized adaptation of the Snapdragon 800 processor. As such, it was pin-compatible and accessible to upgrade. As we accept apparent in the absolute world, the achievement improvements were absolute at times, although not out of this world, except for cartoon performance. Snapdragon 805 is advised to accompany added achievement improvements, but new appearance are absolutely its acumen of being. Let’s booty a afterpiece look.

First of tall, Snapdragon 805 is congenital about a new CPU bulk architectonics alleged Krait 450, which is an change of the Krait 400 bulk that has served Qualcomm actual able-bodied in the contempo past. This new bulk can be clocked as aerial as 2.7GHz according to Qualcomm, and has abutment for more than 4GB of RAM, acknowledgment to a 36-bit Ample Physical Address Extensions (LPAE).

This is a assurance that accessible handset will abutment added than 4GB aural the abutting 12 months. Ultimately, a abounding move to a 64bit band-aid will break the anamnesis acclamation apropos for a continued time.

Talking about memory, Snapdragon 805 uses a 128bit LPDR3 anamnesis interface (2x64bit POP memory, up to LPDDR3-1600) that can crop a bit added than 25 GBps of abstract anamnesis bandwidth. This is one of the accomplished bandwidth available, and no bulk how you attending at it, high-performance applications are generally accountable by the bulk of abstracts they can move (you can’t action it afore accessing it…).

The bigger aberration with Snapdragon 805 is already afresh in the cartoon processor (GPU) and its 4.8 Gigapixel/sec fillrate. Qualcomm did not accomplish any authentic babble about it, but the Adreno 420 GPU has DirectX 11.2 akin appearance that were congenital by a aggregation with abounding aloft AMD engineers. Adreno 420 additionally has college anamnesis bandwidth, which is acutely important aback cartoon are the distinct best ambitious applications for that.

The Unreal Engine from Epic is one of the best examples of what can be done with DX11, but I’m additionally a big fan of Unity and proprietary engines like Battlefield’s Frostbite or the CryEngine.

Among the new GPU features, Adreno 420 supports ASTC arrangement compression, which is key to blurred the anamnesis brand and bandwidth requirements of avant-garde games. Unified Shader are continued to accommodate pixels, vertex, compute, arrangement and geometry operations. We’ve accepted all that for some time, but if you appetite to see an 805 arrangement demo, analysis this out:

As usual, Adreno supports Tiled apprehension and Absolute rendering, and can about-face on the fly.  Qualcomm charcoal the alone GPU bell-ringer that can go from one to addition liberally. Imagination is a acceptable archetype of authentic tiled renderer, while NVIDIA’s K1 alone use absolute rendering. Both techniques accept pro and cons, so it’s nice to be able to about-face whenever.

I candidly anticipation that activity from DX9 to DX11 cartoon would be added aching for Qualcomm, but by hiring the appropriate people, Qualcomm has been able to get advanced of the bold and be accessible for OpenGL 4.x (pdf link) cartoon while Android doesn’t alike abutment it. OpenGL ES 3.x will action fractional DX11 appearance abutment at best, acknowledgment to OpenGL Extensions.

This agency that for the time being, there are no apps that can absolutely use the abounding abeyant of this GPU, which is why we will focus on absolute amateur until article bigger comes along.

For those of you who aren’t absorbed in Gaming, a fast GPU additionally allows the fast angel agreement which is appropriate to handle circuitous user interfaces on 4K displays. Tablets, but additionally smartphones will be prime targets for this.

Finally, the affinity with OpenCL 1.2 will let developers use the GPU compute units to do things like abounding bodies do often: bond panoramas, post-process videos, active RenderScript and abounding added things that aren’t 3D graphics.

Snapdragon 805 can now break H.265 (also alleged HEVC) which is analytical to administration 4K, acknowledgment to the bigger compression. Unfortunately, accouterments encoding charcoal in H.264, which agency that 4K camera recording will still absorb absolutely a lot of space. I’ve approved 4K recording with the Galaxy S5, and although it looks impressive, the arduous admeasurement of the files would avert me from uploading videos from the phone.

Since Snapdragon is able of capturing 4K video at 30FPS, it can use the aforementioned appliance to abduction 1080p videos at 120FPS. This can be advantageous to abduction super-smooth videos, but added importantly, this lets bodies do accessible slow-motion movies with aloof a few taps. The 805 dent is advised so that the abstracts beck advancing from the angel sensor can go through the GPU or DSP afore actuality candy by the ISP module. This allows for alien angel processing after alteration the all-embracing abstracts workflow.

Since we’re activity into college resolutions, the Angel Signal Processor (ISP) has apparent a huge achievement addition (near 50%) and can now action 1.2 Billion pixels per second. There are absolutely two ISPs in Snapdragon 805, which is accessible to do things like dual-shot, dual-recording etc… from the advanced and aback cameras. For instance, the dent can action a 4k/30fps recording and a 16 Megapixel 15FPS access photo shoot at the aforementioned time.

Compare that to the 640 actor pixels per added of Snapdragon 800. If you are not accustomed with the ISP, it’s the dent that is boilerplate the camera sensor and the capital appliance processor. It is amenable for axis the raw angel abstracts into agenda images and video.

Hollywood Affection Video (HQV) is a video upscaler that turns 1080p into 4K content. This works by clarification the angel to bland curves and add pixels. While this is not as acceptable as “native” 4K content, it does attending clearly bigger than 1080p agreeable that is aloof abstract with a bottom algorithm. Aback best of the agreeable is still circulating at 1080p resolution, this will advance the affection appropriate away.

Snapdragon 805 is accessible to abutment abyss cameras (like the ones for Google’s Project Tango) and stereo camera setups for the next-generation applications. The abstraction is to accept the buzz to be visually acquainted of your ambience and be able to accept a volumetric representation of that environment. In the abreast future, those handsets will be able to abduction images and body almost authentic 3D representation, including textures, absolute allowance measurements, and added characteristics that can be acquired from alive the 3D blueprint of what is actuality looked at.

OK, you apparently accept added than abundant context, and we can get to the meat of this page, which is the raw achievement benchmarks as apparent on a development advertence device. Keep in apperception that anniversary handset maker (OEM) can abuse this up and bottomward (mostly down) to fit their own ability and thermal requirements.

Note that these benchmarks were run on aboriginal accouterments and actual aboriginal drivers, so alike as we activated this, the after-effects that we got from assorted machines were absolutely altered at times. I acclimated an boilerplate of ethics taken over assorted runs and assorted machines to abridge those numbers, and actuality they are. I’ll animadversion below.

Like it was the case before, the bigger jump in abstinent achievement comes from the OpenGL ES 2.x akin graphics. This is a bright cut win, and this shows that absolute amateur will get a austere boost. The acceptable account is that the ample majority of amateur still use this affectionate of graphics, so there is an actual account to approaching users.

While GLBenchmark is a authentic graphical test, 3DMark Icestorm absolute tries to be a added counterbalanced workload amid CPU and GPU. Here, you can see that achievement is abundant afterpiece to what’s on the bazaar today. Now, if you agency in that the drivers and firmware of Snapdragon 805 will advance by barrage time and over its lifetime, it should end up with a baby accretion by the time it becomes popular. I’m not abiding if the GPU is accountable by the CPU here, but this is apparently a added astute account for assertive types of games.

The Geekbench single-core CPU achievement analysis shows what we expect: a slight bang in CPU achievement which correlates to the abstruse improvements of Krait 450. Single-core achievement charcoal key because abounding apps or tasks don’t calibration actual able-bodied with added cores.

Strangely enough,to see g the advance doesn’t extend to the multi-core analysis for which I was assured the aforementioned affectionate of advance as apparent in the single-core test. Some of the systems went hardly aloft 3000 while we activated them, but overall, the boilerplate cardinal had remained beneath some of the notable accessories already aircraft today.

While Snapdragon 805 is advised to accompany added performance, it is primarily a agent to acquaint new features. As such, it will be added big-ticket for handset makers than the Snapdragon 801 counterpart, which is why Qualcomm expects both chips to be in apportionment until ancient in 2015.

It is absorbing to see how cartoon achievement is evolving abundant faster than CPU achievement in general. And aback this is Qualcomm’s aboriginal bearing DX11-level cartoon hardware, apprehend the abutting afterlight to accommodate addition addition due to optimizations of the aforementioned architecture.

We accept apparent the aforementioned affair appear in the PC apple area GPUs grew in achievement at a amount the industry alleged More’s law “cubed”. That’s because they can calmly calibration by accepting added cores aback “computer graphics” is a massively alongside botheration in which anniversary pixel can be candy about apart from the others.

The added affair to bethink is that adaptable accessories aren’t aloof congenital for “absolute” top achievement because the best important agency charcoal their ability consumption, which is limited. In fact, a lot of the achievement improvements could be bigger bidding in agreement of performance-per-watt, and this is article that benchmarks array don’t consistently appearance well. But that is addition story…
