Ja tā ir taisnība par PS4, tad izskatās, ka Sony baidās no Nintendo un Microsoft jaunajiem dzelžiem. Anyway gaidu jaunumus no E3 izstādes (tos gan šogad uzzināšu tikai kaut kad septembrī).

Būs pa vasaru jāvergo ASV (internship). Pie interneta laikam tikšu reizi nedēļā un prioritāte tad būs izlasīt/atbildēt e-pastus. Gan jau, ka kaut ko izdosies par E3 izlasīt.

Mjā, jo mēs visi zinam, ka free internet jomā ASV ir uzreiz aiz Ziemeļkorejas...

Based on developer sources following CES 2013, the report states that the next PlayStation, codenamed Orbis, will have a running-capability of 1.84 teraflops. That compares favourably with the next Xbox, codenamed Durango, which is reported to achieve 1.23 teraflops.

Despite this, however, the report also states that the Xbox 720 will have significantly more RAM. The machine will have 8Gb of RAM, with 3Gb sidelined for the operating system, apps and security.That leaves 5Gb purely for games.

The PlayStation 4, meanwhile, is reported to have 4Gb of RAM, of which 1Gb is reserved for the OS, apps and security, leaving 3Gb for games.

It is also said that both machines will have the ability to read 100Gb Blu-ray discs.

The Xbox 720 is reportedly based on the Radeon HD 8770 GPU, while PlayStation 4 is said to be built on AMD’s A10 APU.

Es tikai varu pakomentēt, ja ar 512 mb xbox iet tīri labi, kā tad ies ar 8 gb ram? :) Skype jebkurā gadījumā ir labāks par XBL čatu!

VGleaks publicēja šo: http://www.vgleaks.com/world-exclusive- ... nveiled-2/
Baumas jāuztver ar zināmu piesardzību, taču šis atbilst iepriekš lasītajam no citiem avotiem. 8GB DDR3 (68GB/s) un 32MB ESRAM (102GB/s) kā arī atsevišķš Data Move Engines, kas tiek minēts, ka nodrošinās atmiņas sadalījumu starp DDR3 un ātrāko ESRAM. Salīdzinot šo ar baumām par PS4 (Orbis), var redzēt ka Microsoft un SONY izvēlas divas atšķirīgas pieejas. Microsoft nākamajam XBOX spiež uz RAM daudzumu, tā ir 2x vairāk nekā PS4 (Orbis), savukārt SONY spiež uz atmiņas ātrumu, par Orbis baumo, ka visi tā 4GB būs GDDR5 (lēsts ap 192GB/s). Kura pieeja ilgtermiņā dos labāku rezultātu tieši spēlēm, redzēsim tikai pēc kādiem gadiem 3-5. Citi avoti arī apraksta būtiski atšķirīgu atmiņas daudzumu, kas rezervēts operētājsistēmai. Interesanti, ka MS izmantos tieši to pašu atmiņu, kas jau ir XBOX360, tikai palielinās tās daudzumu, tas varētu nozīmēt, ka Durango pašizmaksa būs lētāka nekā PS4 un Microsoft ātrāk nonāks pie peļņas no pārdotajām konsolēm.

Vēl kas interesants no VGleaks materiāla: Durango specifikācijā ir HDMI ieejas ports, kas iespējams nozīmē, ka tam varēs pieslēgt ārēju video avotu, kā piemēram Lattelecom vai Comcast dekoderi. Tas savukārt varētu nozīmēt, ka Microsoft nākamo XBOX iecerējuši kā universālu media centru ar TV satura ierakstīšanas un saglabāšanas funkcionalitāti (TiVo, DVR).

Pienācis laiks arī Orbis (PS4) noplūdei no VGleaks: http://www.vgleaks.com/world-exclusive-orbis-unveiled/

Neko jaunu gan neredzu, pārsvarā jau iepriekš zināmās lietas:

LIVERPOOL SOC:
Custom implementation of AMD Fusion APU Arquitecture (Accelerated Processing Unit)
Provides good performance with low power consumtion
Integrated CPU and GPU
Considerably bigger and more powerful than AMD’s other APUs

CPU:
Orbis contains eight Jaguar cores at 1.6 Ghz, arranged as two “clusters”
Each cluster contains 4 cores and a shared 2MB L2 cache
256-bit SIMD operations, 128-bit SIMD ALU
SSE up to SSE4, as well as Advanced Vector Extensions (AVX)
One hardware thread per core
Decodes, executes and retires at up to two intructions/cycle
Out of order execution
Per-core dedicated L1-I and L1-D cache (32Kb each)
Two pipes per core yield 12,8 GFlops performance
102.4 GFlops for system

GPU:
GPU is based on AMD’s “R10XX” (Southern Islands) architecture
DirectX 11.1+ feature set
Liverpool is an enhanced version of the architecture
18 Compute Units (CUs)
Hardware balanced at 14 CUs
Shared 512 KB of read/write L2 cache
800 Mhz
1.843 Tflops, 922 GigaOps/s
Dual shader engines
18 texture units
8 Render backends
Each CU contains dedicated:
- ALU (32 64-bit operations per cycle)
- Texture Unit
- L1 data cache
- Local data share (LDS)

About 14 + 4 balance:
- 4 additional CUs (410 Gflops) “extra” ALU as resource for compute
- Minor boost if used for rendering

Dual Shader Engines:
- 1.6 billion triangles/s, 1.6 billion vertices/s

18 Texture units
- 56 billion bilinear texture reads/s
- Can utilize full memory bandwith

8 Render backends:
- 32 color ops/cycle
- 128 depth ops/cycle
- Can utilize full memory bandwith

Memory:
4 GB unified system memory, 176 GB/s
3.5 available to games (estimate)

Storage:
- High speed Blu-ray drive
single layer (25 GB) or dual layer (50 GB) discs
Partial constant angular velocity (PCAV)
Outer half of disc 6x (27 MB/s)
Inner half varies, 3.3x to 6x
One SKU at launch: 500 GB HDD
There may also be a Flash drive SKU in the future

Networking:
1 Gb/s Ethernet, 802.11b/g/n WIFI, and Bluetooth

Peripherals:
Evolved Dualshock controller
Dual Camera
Move controller

Extra:
Audio Processor (ACP)
Video encode and decode (VCE/UVD) units
Display ScanOut Engine (DCE)
Zlib Decompression Hardware

Neko daudz no teim cipariem un burtu abreviatūrām es nesaprotu, taču citos forumos un blogos šī specifikācija, salīdzinot ar nākamo XBOX tiek saukta par "diezgan līdzvērtīgu". Ir nedaudz labāks GPU un krietni ātrāka atmiņa, taču kā jau iepriekš bija zināms, tās daudzums ir mazāks. Priecē, ka OS ir rezervēti tikai 500MB no atmiņas apjoma, tātads ļoti kompakts "footprint" līdzīgi kā tas ir PS Vita. Grūti iedomāties, ka visi šie labumi maksās mazāk par $400.

SONY plāno atklāt savas kārtis atsevišķā konferencē pirms februāra beigām! Krietni pirms E3.

Dzelži izklausās labi. Cerams, ka kaut kad redzēsim arī spēles, kas spēs hārdvēru izmantot, lai sniegtu jaunu, iepriekš neredzētu geiminga pieredzi.

Eurogamer publicējis interesantu salīdzinājumu starp abām konsolēm: http://www.eurogamer.net/articles/df-ha ... o-vs-orbis

Vērts izlasīt visu rakstu.

Sony hardware has a surprisingly large 32 ROPs (Render Output units) up against 16 on Durango. 16 ROPs is sufficient to maintain 1080p, 32 comes across as overkill, but it could be useful for addressing stereoscopic 1080p for instance, or even 4K


we see a great deal of commonality between the two systems as engineers posed with the same problems come up with similar solutions


ramming 8GB of the fastest memory into a console box simply isn't logistically possible. A key Xbox 360 advantage over PS3 was a unified pool of 512MB of fast GDDR3 memory. GDDR5 is the latest equivalent, used principally in PC graphics cards, but the problem here is that the modules only come in certain capacities - the largest and most difficult to produce being 512MB


whichever way Microsoft tries to finesse it, the 32MB of ESRAM is a bit of a sticking plaster solution that is nowhere near as fast or efficient as the single unified pool of RAM available to Orbis


while some appear to be worried that being locked to the Microsoft API will be an issue, the fact is that there are specific DX11 functions available to devs tied into the custom Durango hardware. There's also a level of flexibility in how DirectX is used that is equivalent to the almost legendary concept of "coding to the metal"


With regards the next-generation PlayStation, developers are highly unlikely to have the same kind of issues with the toolchain that they had with PS3. Having acquired SN Systems back in 2005, principally to improve the development environment for their consoles, we're told that the quality of the tools has increased exponentially to the point where one highly experienced game-maker we spoke to rates the PlayStation Vita tools as the most impressive he's used.


it's no real surprise that both Microsoft and Sony have acquired very similar parts from the same vendor, based on existing technology


On paper, Orbis looks like the tighter, more powerful, more games-focused design


the astonishing lengths to which Microsoft has gone to accommodate 8GB of RAM adds further weight to the hypothesis that its plans for the Xbox hardware extend beyond gaming
