Project X Logan K1 is the first big news out of CES from NVIDIA and represents a bit of a change from what we were expecting. The current belief was that the SoC would have four 28nm Cortex A15 processors but that will only be one flavour of K1, a Denver based dual core version will also be released. Those ARMv8 64-bit processors will natively handle 64 bit applications while the A15 version that The Tech Report had taken pictures of will be limited to 32 bit applications, though that will not matter in many mobile applications. You should also check out Ryan's deep dive into the new Denver and Kepler version here.
"In early 2011, during a CES press event, Nvidia revealed its Project Denver CPU initiative. On Sunday evening, at another CES press conference, the company provided a glimpse of the first Denver-based processor: the Tegra K1. This next-generation SoC features dual Denver CPU cores clocked at up to 2.5GHz. The cores were designed by Nvidia, and they're compatible with the 64-bit ARMv8 instruction set. They have a seven-way superscalar pipeline and a hefty 192KB of L1 cache."

Once known as Logan, now known as K1
NVIDIA has bet big on Tegra. Since the introduction of the SoC's first iteration, that much was clear. With the industry push to mobile computing and the decreased importance of the classic PC design, developing and gaining traction with a mobile processor was not only an expansion of the company’s portfolio but a critical shift in the mindset of a graphics giant.
The problem thus far is that while NVIDIA continues to enjoy success in the markets of workstation and consumer discrete graphics, the Tegra line of silicon-on-chip processors has faltered. Design wins have been tough to come by. Other companies with feet already firmly planted on this side of the hardware fence continue to innovate and seal deals with customers. Qualcomm is the dominant player for mobile processors with Samsung, MediaTek, and others all fighting for the same customers NVIDIA needs. While press conferences and releases have been all smiles and sunshine since day one, the truth is that Tegra hasn’t grown at the rate NVIDIA had hoped.
Solid products based on NVIDIA Tegra processors have been released. The first Google Nexus 7 used the Tegra 3 processor, and was considered the best Android tablet on the market by most, until it was succeeded by the 2013 iteration of the Nexus 7 this year. Tegra 4 slipped backwards, though – the NVIDIA SHIELD mobile gaming device was the answer for a company eager to show the market they built compelling and relevant hardware. It has only partially succeeded in that task.
With today’s announcement of the Tegra K1, previously known as Logan or Tegra 5, NVIDIA hopes to once again spark a fire under partners and developers, showing them that NVIDIA’s dominance in the graphics fields of the PC has clear benefits to the mobile segment as well. During a meeting with NVIDIA about Tegra K1, Dan Vivoli, Senior VP of marketing and a 16 year employee, equated the release of the K1 to the original GeForce GPU. That is a lofty ambition and puts of a lot pressure on the entire Tegra team, not to mention the K1 product itself, to live up to.
Tegra K1 Overview
What we previously knew as Logan or Tegra 5 (and actually it was called Tegra 5 until just a couple of days ago), is now being released as the Tegra K1. The ‘K’ designation indicated the graphics architecture that powers the SoC, in this case Kepler. Also, it’s the first one. So, K1.
The processor of the Tegra K1 look very familiar and include four ARM Cortex-A15 “r3” cores and 2MB of L2 cache with a fifth A15 core used for lower power situations. This 4+1 design is the same that was introduced with the Tegra 4 processor last year and allows NVIDIA to implement a style of “big.LITTLE” design that is unique. Some slight modifications to the cores are included with Tegra K1 that improve performance and efficiency, but not by much – the main CPU is very similar to the Tegra 4.
NVIDIA also unveiled late last night that another version of the Tegra K1 that replaces the quad A15 cores with two of the company's custom designs Denver CPU cores. Project Denver, announced in early 2011, is NVIDIA's attempt at building its own core design based on the ARMv8 64-bit ISA. This puts this iteration of Tegra K1 on the same level as Apple's A7 and Qualcomm's Krait processors. When these are finally available in the wild it will be incredibly intriguing to see how well NVIDIA's architects did in the first true CPU design from the GPU giant.

Update: Check out our more in-depth analysis of the Tegra K1 processor from NVIDIA.
Today during its CES 2014 press conference, NVIDIA announced the Tegra K1 SoC as the successor to the Tegra 4 processor. This new ARM-based part includes 192 Kepler-based CUDA cores, sharing the same GPU architecture as the current GeForce GTX 700-series discrete graphics cards.
NVIDIA also announced the Epic has Unreal Engine 4 up and running on the Tegra K1, bringing an entirely new class of games to mobile Android devices. We got to see some demonstrations from NVIDIA running on the K1 and I must admit the visuals were stunning. Frame rates did get a bit choppy during the subway demo of UE4 but it's still early.
As an added surprise, NVIDIA is announcing a version of Tegra K1 that ships with the same quad-core A15 (4+1) design as the Tegra 4 BUT ALSO have a version that uses two NVIDIA Denver CPU cores!! Denver is NVIDIA's custom CPU design based on the ARMv8 architecture, adding 64-bit support to another ARM partner's portfolio.
Tegra K1 is offered in two pin-to-pin compatible versions - a 32-bit quad-core (4-Plus-1 ARM Cortex-A15 CPU) and a custom, NVIDIA-designed 64-bit dual Super Core CPU. This CPU (codenamed “Project Denver”) delivers very high single-thread and multi-thread performance. Both versions deliver stunning graphics and visual computing capabilities powered by the 192-core NVIDIA Kepler GPU.
NVIDIA has only had Denver back for a few days from the fab but there able to showcase it running Android. It's been a long time since the initial announcement of this project and its great to finally see a result.

Intel spilled more beans about the new Near Memory architecture that will be accompanying their new Xeon release. The memory will be stacked directly onto the CPU giving much quicker access than you would normally see from DDR3 which has to travel over the motherboard. They have not disclosed expected speeds, which could be up to what we see in current CPU caches only in much larger sizes. This is not quite a Xeon SoC but in the presentation The Register heard of Intel's plans to incorporate optical fabrics and switches onto the CPUs as well with size being the only limit. Perhaps they do have a leg to stand on when they claim the return to power of homogeneous computing.
"According to an EE Times report, Intel's Rajeeb Hazra, a VP and general manager of its data centre group, said Intel would customise high-end Xeon processors and Xeon Phi co-processors by closely integrating memory, both by adding memory dies to a processor package and, at a later date, integrating layers of memory dies into the processor along with optical fabrics and switches."

Tagged: SoC, p5600, MIPS, imagination
Imagination Technologies, a company known for its PowerVR graphics IP, has unleashed its first Warrior P-series MIPS CPU core. The new MIPS core is called the P5600 and is a 32-bit core based on the MIPS Release 5 ISA (Instruction Set Architecture).
The P5600 CPU core can perform 128-bit SIMD computations, provide hardware accelerated virtualization, and access up to a 1TB of memory via virtual addressing. While the MIPS 5 ISA provides for 64-bit calculations, the P5600 core is 32-bit only and does not include the extra 64-bit portions of the ISA.
The MIPS P5600 core can scale up to 2GHz in clockspeed when used in chips built on TSMC's 28nm HPM manufacturing process (according to Imagination Technologies). Further, the Warrior P5600 core can be used in processors and SoCs. As many as six CPU cores can be combined and managed by a coherence manager and given access to up to 8MB of shared L2 cache. Imagination Technologies is aiming processors containing the P5600 cores at mobile devices, networking appliances (routers, hardware firewalls, switches, et al), and micro-servers.
A configuration of multiple P5600 cores with L2 cache.
I first saw a story on the P5600 over at the Tech Report, and found it interesting that Imagination Technologies was developing a MIPS processor aimed at mobile devices. It does make sense to see a MIPS CPU from the company as it owns the MIPS intellectual property. Also, a CPU core is a logical step for a company with a large graphics IP and GPU portfolio. Developing its own MIPS CPU core would allow it to put together an SoC with its own CPU and GPU components. With that said, I found it interesting that the P5600 CPU core was being aimed at the mobile space, where ARM processors currently dominate. ARM is working to increase performance while Intel is working to bring its powerhouse x86 architecture to the ultra low power mobile space. Needless to say, it is a highly competitive market and Imagination Technologies new CPU core is sure to have a difficult time establishing itself in that space of consumer smartphone and tablet SoCs. Fortunately, mobile chips are not the only processors Imagination Technologies is aiming the P5600 at. It is also offering up the MIPS Series 5 compatible core for use in processors powering networking equipment and very low power servers and business appliances where the MIPS architecture is more commonplace.
In any event, I'm interested to see what else IT has in store for its MIPS IP and where the Warrior series goes from here!

AMD have announced their new mobile roadmap and have changed their naming scheme drastically for these new processors. The first of their ARM based processors will be called Hierofalcon and feature up to eight Cortex A57 processors capable of hitting 2GHz with a pair of 64-bit ECC DDR3 or DDR4 memory channels. It will be a true SoC and feature both network and PCIe controllers as well as support for ARM's TrustZone. Bald Eagle will have Steamroller cores and will be low TDP processors with a maximum of 35W and allow you to configure the maximum TDP to even lower levels if you so wish. The final announcement dealt with the new GCN-based embedded series of GPUs called Adelaar which arrive in three different packages, a multi-chip module, a mobile PCIe module and a discrete GPU. You can glean a bit more about these new families at DigiTimes.
"AMD has disclosed its roadmap for the embedded computing market, as it becomes the first company to offer both ARM and x86 processor solutions for low-power and high-performance embedded compute designs. The new lineup includes two x86 accelerated processing units (APUs) and CPUs, a high-performance ARM system-on-chip (SoC) and a new family of discrete AMD Embedded Radeon graphics processing units (GPUs) expected to launch in 2014."

Tagged: xbox one, SoC, microsoft, gaming, console, amd
At the Hot Chips conference earlier this week, Microsoft showed off several slides detailing the SoC used in its upcoming Xbox One gaming console.
The Xbox One uses a System on a Chip (SoC) designed by AMD’s Semi-Custom Business Unit. The processor features eight “Jaguar” AMD CPU cores, an AMD GCN (Graphics Core Next) based GPU with 768 shader cores, an audio co-processor, and 32MB of on-chip eSRAM.
The SoC, measuring 363mm^2 is manufactured on TSMC’s 28nm HPM process. The chip can interface with 8GB of DDR3 main memory with bandwidth of 68.3 GB/s or utilize the on-chip SRAM which has bandwidth of 102GB/s. The embedded SRAM is in addition to the smaller L1 and L2 caches. The slides indicate that the GPU and CPU can at least access the SRAM, though it still remains frustratingly unknown if the SoC supports anything like AMD’s hUMA technology which would allow the CPU and GPU to both read and write to the same memory address spaces without having to copy data between CPU and GPU-accessible memory space. It may be that the CPU and GPU can use the SRAM, but the same memory spaces can not be shared, though that may be the pessimist in me talking. On the other hand, there could be something more, but it’s impossible to say from the block diagram spotted by Semi-Accurate at the Microsoft presentation.
With that said, the slides do reveal a few interesting figures about the SoC that were not known previously. The Xbox One SoC has 47MB of on-chip memory including 32MB eSRAM used by the CPU and GPU and 64KB of SRAM used by the audio co-processor. The chip’s GPU is rated for Microsoft’s DirectX 11.1 and above graphics API. Further, Microsoft rates the GPU at 1.31 TFLOPS, 41 Gigatexels-per-second, and 13.6 Gigapixels-per-second. Additionally, the GCN-based GPU is able to hardware-encode multi-stream H.264 AVC MVC video and hardware decode multiple formats, including H.264 MVC. The hardware encoder is likely being used for the console’s game capture functionality.
The audio processors in the Xbox One SoC use two 128-bit SIMD floating point vector cores rated at 15.4 GFLOPS and “specialized hardware engines” and “signal processing optimized vector and scalar cores.”
The final interesting specification I got from the slides was that the SoC is able to go into a low power state that is as low as 2.5% of the chip’s full power using power islands and clock gating techniques.
You can find all of the geeky details in these slides over at SemiAccurate.

Tagged: valleyview, SoC, silvermont, pentium, Intel, celeron, Bay Trail, atom
A leaked Intel lineup reveals that the company's upcoming Bay Trail processors will also fall under not only the traditional Atom branding, but the Pentium and Celeron brands as well. The new lineup includes Bay Trail-D, Bay Trail-I, and Bay Trail M processors (note that Valleyview is the CPU codename, Bay Trail is the platform codename, with the CPU based on Intel's 22nm Silvermont architecture). The Bay Trail SoCs, which are based on the company's new 22nm Silvermont micro-architecture, include five processors in the Atom family, two in the Pentium family, and five processors that are part of the Celeron family.
All five of the Atom branded processors are Bay Trail-I chips. The leaked Atom lineup includes the following SKUs.
- Atom E3810 (Bay Trail-I): Single core at 1.46 GHz with 400 MHz GPU and 5W TDP
- Atom E3821 (Bay Trail-I): Dual core at 1.33 GHz with 533 MHz GPU and 6W TDP
- Atom E3822 (Bay Trail-I): Dual core at 1.46 GHz with 667 MHz GPU and 7W TDP
- Atom E3823 (Bay Trail-I): Dual core at 1.75 GHz with 792 MHz GPU and 8W TDP
- Atom E3840 (Bay Trail-I): Quad core at 1.91 GHz with 792 MHz GPU and 10W TDP
Further, there will be one Bay Trail-M and one Bay Trail-D Silvermont-based CPU under the Pentium brand. Specifications on those two chips are below.
- Pentium N3510 (Bay Trail-M): Quad core at 2 GHz with 750 MHz GPU and 7.5W TDP (4.5W SDP)
- Pentium J2850 (Bay Trail-D): Quad core at 2.41 GHz with 792 MHz GPU and 10W TDP
Finally, the new Bay Trail-M and Bay Trail-D SoCs under the Celeron brand includes two quad cores and three dual core CPUs.
According to this PDF, the N2805, N2810, and N2910 Celeron CPUs will have an MSRP of $132, though it seems as though the N2805 should be cheaper than that since it has much lower specifications than the other two. The new Celeron-branded chips have the following specifications.
- Celeron J1750 (Bay Trail-D): Dual core at 2.41 GHz with 792 MHz GPU and 10W TDP
- Celeron J1850 (Bay Trail-D): Quad core at 2 GHz with 792 MHz GPU and 10W TDP
- Celeron N2805 (Bay Trail-M): Dual core at 1.46 GHz with 667 MHz GPU and 4.5W TDP (sub-2.5W SDP)
- Celeron N2810 (Bay Trail-M): Dual core at 2 GHz with 756 MHz GPU and 7.5W TDP (4.5W SDP)
- Celeron N2910 (Bay Trail-M): Quad core at 1.6 GHz with 756 MHz GPU and 7.5W TDP (4.5W SDP)

Tagged: SoC, KBN-I, Kabini, ECS, A6-5200
ECS' new KBN-I board simply needs you to add some RAM and storage to become a fully functional computer. The integrated 2.0Ghz A6-5200 with its accompanying HD 8400 graphics are enough power for general computing duties and perhaps even newer titles if you turn the settings down somewhat. If you do plan on gaming there is a PCIe 3.0 16x slot for an expansion card, though you might be better served with a TV capture card instead of a graphics card.
19th Jun 2013, Taipei, Taiwan - Elitegroup Computer Systems (ECS) reveals its latest Mini-ITX motherboard family－KBN-I－featuring the world 1st Quad Core SoC (system-on-a-chip) processor with the newest “Jaguar” 28 nanometer architecture.

Tagged: Intel, atom, Clover Trail+, SoC, Samsung, Galaxy Tab 3 10.1
While Reuters is being a bit cagey with their source, if true: Intel may have nabbed just about the highest profile Android tablet design win possible. The, still currently unannounced, Samsung Galaxy Tab 3 10.1 is expected to embed Intel's Clover Trail+ System on a Chip (SoC). Samsung would not be the largest contract available in the tablet market, their previous tablets ship millions of units each; they are a good OEM vendor to have.
Source: BGR India
Samsung is also known for releasing multiple versions of the same device for various regions and partners. The Galaxy Tab 10.1 and Galaxy Tab 2 10.1 did not have a variety of models with differing CPUs like, for instance, the Galaxy S4 phone did; the original "10.1" contained an NVIDIA Tegra 2 and the later "2 10.1" embed a TI OMAP 4430 SoC. It is entirely possible that Intel won every Galaxy Tab 3 10.1 tablet ever, but it is also entirely possible that they did not.
Boy Genius Report India (BGR India, video above) also claims more specific hardware based on a pair of listings at GLBenchmark. The product is registered under the name Santos10: GT-P5200 being the 3G version, and GT-P5210 being the Wi-Fi version.
These specifications are:
- Intel Atom Z2560 800-933 MHz dual-core SoC (4 threads, 1600 MHz Turbo)
- PowerVR SGX 544MP GPU (OpenGL ES 2.0)
- 1280x800 display
- Android 4.2.2
I am not entirely sure what Intel has to offer with Clover Trail+ besides, I would guess, reliable fabrication. Raw graphics performance is still about half of Apple's A6X GPU although, if the leaked resolution is true, it has substantially less pixels to push without being attached to an external display.
Maybe Intel made it too cheap to refuse?
