Some actual hard numbers !

That might shut down some clueless Nvidia haters for a moment. Seems like Qualcomm isn't so mighty like their CMO said after all
I hope to see a great tablet from Asus tomorrow !

Yea I think he just swallowed his tongue

Considering both the T4 and T4i have the same GPU but with reduced ALUs, 72 vs 60

We can assume 47fps for Tegra 4i sadly we don't know yet if its dual channel memory or not, otherwise such score would be impossible

Keeping In mind these T4 scores are from exposed development boards which mean it might be heavily OCed still pretty damn impressive!

Very, very impressive! Could you imagine a new Nexus 7 with that beast inside? :laugh: :good:

So Hamdir are you still getting the One or are you waiting for something with this inside?

hot_spare · Feb 24, 2013

Add about 4166 in Geekbench score!

Mighty impressive to say the least.

Sadly so sadly we don't have devices, even the next nexus 7 is said to go with Qualcomm

Lets wait and see what MWC will reveal

As for the One I can only survive with HTC's smartphones and they opted for snapdragon, Tegra 4i is far off according to Nvidia's own words

I will get the One in silver enjoy it and then hand it over to my wife if an HTC t4 appears, otherwise ill keep it n get myself a tablet, can't wait to get rid of my silly iPad4

Tegra 4, excellent Sunspider Scores, which I expected as A15 is good at javascript. When we look at the graphics section of Quadrant, Tegra 4 is not much faster, in fact it is slower in 2D.

The GLBenchmark score we must treat with CAUTION, it is not the same as the original Eygpt HD offscreen. It appears to be using a new texture type. The new test listed is called C24Z16 Offscreen ECT1, the one we know for iPad 4 etc is called C24Z16 Offscreen , we don't how this new texture type affects performance it could make faster or slower, I've emailed the GLB people to find out. Still I would not mind the T4 in a new Nexus 7, as I mainly web browse on it.

With n3o new kernel you can oc your gpu now... Maybe this will be useful for some heavy gamer(especially to shan89, that guy asked for 560mhz gpu a million times

)

An yes I noticed but didn't think much of it, maybe they are using their hardware supported DXT texture compression format (which reduces strain on bandwidth)

Excellent feedback my friend thanks for providing some perspective

Since t4i is still far from ready and not benched, this news only concerns tablets, A15 is clearly not viable in smartphones, therefore HTC One is not really affected but it was nice from Nvidia to punch Qualcomm for their nonsense

Who are we fooling we all love Nvidia

By the way, looking back at the quadrant scores, I'm surprised Tegra is achieving the massive increase purely from CPU, I won't give much importance to 2D since the 2D clock might be DCed but the memory and IO are extremely similar to the One, despite the stated DDR2 on the One

kokusho · Feb 24, 2013

I ve always find quadrant to be a very bad benchmark.
Its scores never makes sense at all, and the CPU part account for way to large portion of the total score.

I don't care too much about battery life in a tablet, so I would love a T4 in a Nexus 7. I think with T4, we are also seeing Nvidia's software knowledge, they seem to optimise for javascript performance far better than Qualcomm.

Excellent in-depth analysis of Tegra 4 from Anandtech. Am I the only one imagining Tim Cook from Apple, reading the T4 graphics benchmarks, whilst stroking a Power VR 6 Rogue GPU

nvidia is showing two boards for the Phoenix reference one with Tegra 4 in the middle and another Tegra 4i in the right

Nvidia solved the heat issue by moving the board away from the battery by placing it at the side

nvidia is clearly aiming full Tegra 4 at super smartphones

AndroidPolice: [Eyes-On] Tegra 4, Tegra 4i, And The Phoenix Reference Phone At MWC 2013 (With Benchmarks And Stats)

And this bit from Anandtech reveals how they are planning to put it in a smartphone

Anandtech: NVIDIA Tegra 4 Architecture Deep Dive, Plus Tegra 4i, Icera i500 & Phoenix Hands On

What this data does tell us however is exactly how NVIDIA plans on getting Tegra 4 into a phone: by aggressively limiting frequency. If a Cortex A15 at 825MHz delivers identical performance at a lower power compared to a 40nm Cortex A9 at 1.6GHz, it’s likely possible to deliver a marginal performance boost without breaking the power bank.

And this explains my calculations, I originally calculated 600mhz to achieve 50fps, but they went with higher clocks for a higher score

The Tegra 4 GPU operates at up to 672MHz, up from the 520MHz max in Tegra 3.

Tons of info about the GPU here:

Best bit, Tegra 4i GPU increasingly favors pixels ratio, 48 pixel shaders and 12 vertex and a new L2 cache on both T4 GPU

However they don't support ES 3.0 given they are aimed at 2013 its a disadvantage, and T4i is single channel...

With Tegra 4, complaints about memory bandwidth can finally be thrown out the window. The Tegra 4 SoC features two 32-bit LPDDR3 memory interfaces, bringing it up to par with the competition. The current max datarate supported by Tegra 4’s memory interfaces is 1866MHz, but that may go up in the future

Tegra 4 won’t ship in a PoP (package-on-package) configuration, and will have to be paired with external DRAM. This will limit Tegra 4 to larger devices, but it should still be able to fit in a phone.

Tegra 4i retains the same base GPU architecture as Tegra 4, but dramatically cuts down on hardware. NVIDIA goes from 4 down to 3 vertex units, and moves to two larger pixel shader units (increasing the ratio of compute to texture hardware in the T4i GPU).

The max T4i GPU clock drops a bit down to 660MHz, but that still gives it substantially more performance than NVIDIA’s Tegra 3.

Unfortunately, Tegra 4i only has a single channel LPDDR3 memory interface. Tegra 4i on the other hand will be available in PoP as well as discrete configurations. The PoP configuration may top out at LPDDR3-1600, while the discrete version can scale up to 1866MHz and beyond.

Caution:
However as Turbotab warned, the Egypt HD results are a little suspect since they appear to be using a special texture format (notice the ETC1) and therefore not the standard, maybe Nvidia's own hardware compressed DXT textures

Update:
Tegra 4 in Project shield is scoring 51.9 fps in Egypt HD 2.7 1080p offscreen and 55.2 720p onscreen

Ripetide 2 running on very early T4i

Final Words
NVIDIA’s Tegra 4 is a significant step forward in both CPU and GPU performance. Although Tegra 3 was decent in both areas, Tegra 4 really moves things forward. ARM’s Cortex A15 is an excellent performer, although that performance comes at a high power cost. In a tablet, as we’ve already seen with Google’s Nexus 10, the power consumption associated with the Cortex A15 core is manageable. If NVIDIA’s data is to be believed however, Tegra 4 can get into a smartphone just by aggressively controlling frequencies. At reduced frequencies, Tegra 4 can draw less power than Tegra 3 but with no performance advantage. NVIDIA could then scale up performance (and power) to offer an improvement over Tegra 3. The real question at that point is whether or not Qualcomm’s Krait 300/400 designs offer better efficiency at these intermediate points on the performance/power curve. We’ll be able to find out for sure later this year when both Tegra 4 and Snapdragon 600/800 based devices are shipping.

NVIDIA’s biggest advantage hasn’t been architecture, but rather being in the right design wins. Without a doubt, the Nexus 7 and Surface RT were significant wins for NVIDIA last year and they really helped ensure a successful year for NVIDIA’s Tegra business. Whether or not NVIDIA will be able to guarantee similarly key design wins with Tegra 4 remains to be seen. The architecture looks good enough on paper, now it’s just up to NVIDIA’s sales teams to get it into the right devices.

As feared Tegra 4i will only have single channel memory, but at least its LPDDR3 @ 800 MHz (DDR 1600 MHz), but thats only 6.4 GB/s, how will that bottleneck the GPU, as it's only slightly better than the Nexus 7.

Tegra 4 won't use PoP DRAM, so it has to use external DRAM which increases space requirements, the advantage it can use up 1866 MHz RAM, giving a max bandwidth of 14.9 GB/s.

Hey , can anyone tell me how the "octa" compares to the tegra 4 In terms of gpu power and usage?

Not sure about tegra 4 5th core, TegrA 3 at the 5th had an a7 that consumed less compared to the a9 main cores, but t4 just has the exact same architecture for the lp and main cores, wouldn't that be useless ? Correct me if I'm wrong

Holy **** guys Tegra 4 is insane, I have goose bumps!

Check the benchmarks iDevices are slaughtered

57fps Egypt HD offscreen...I want to cry from happiness, the CPU scores are otherworldly

This beats the best of my predictions

(Engadget made a big mistake the score for Egypt HD offscreen and they are comparing it to classic Egypt on Tegra 3)

Engadget's SunSpider figures are also suspicious, to say the least.

Admittedly not on stock firmware (I'm using a non-Linaro EOS 4 JB ROM), but I get a *vastly* better SunSpider score on my Tegra 2-based TF101 tablet with stock browser, and not overclocked, than they list for the Tegra 3-based Transformer Pad.

In fact, my tablet's score was almost exactly identical to that for the Tegra 3-based Xperia Tablet; somewhere in the low 1,600s.

Wasn't it supposed to come out in Sony's own SoC, the Nova ST something.. When was it supposed to be back then ?
