How do you find the velomobile compares to a road bike? More useful, less useful, or just different?
It's very useful for one single reason: I never have to worry about the weather, and what to wear when it rains, or having to change when I arrive at work in the morning. Also, I can carry a ton of stuff inside, which is great for getting groceries and for touring. And it's quite a bit faster than a road bike on average too. The only downside is, it climbs like a pig. The time lost on the uphill is recovered when going back down, but I ain't gonna race someone going up.
This magical modification of a bike somehow eliminates perspiration?
The only effective way to give less oil money to Saudi Arabia is to buy less oil (and oil-derived products).
Or declare war and steal it.
I guess some random can just say anything and assume it has more merit than someone else's experiences. Given I'm also a random, we're at an impasse here.
In this case, they're an AC and you're not so you get to pull rank
But take for example the Radeon driver (the so called open source one). It takes almost a meg of main memory. The closed source one takes even more memory. Its running all the time that your system is up.
Clearly its not just firmware we are talking about here.
The main memory aspect is taken up by the open source driver code. The firmware blob goes straight to the hardware.
Perhaps. I haven't run the AMD proprietary drivers for a while. When I did, I seem to recall a large binary always running.
The blobs we're talking about here are NOT the AMD proprietary drivers, we're talking about the firmware blobs that the community drivers have to send to the cards at initialization.
So how trivial will it be to slurp the OS out onto a AMD card enabled PC and have our own "HackStation4"?
I'm assuming they meant using an AMD based PC because the drivers already in the PS4 OS might be compatible (which is not particularly likely). Alternatively if you want NVIDIA, they already have an official driver for FreeBSD that you could try hacking into Orbis. Neither case requires a custom Linux-FreeBSD shim.
You would have to write a wrapper around the FreeBSD driver apis for Linux (this may already exist).
Why? You could just run FreeBSD on that PC instead of Linux.
Haswell is not 4 times faster than Ivy Bridge.
But it might be 4 times as fast as what you're running now, especially if you skipped a generation of Intel CPU. Is it four times as fast as Sandy Bridge? Nehalem?
You seem to have completely missed my point. I said Haswell doesn't change anything with regards to thermal challenges in building such SFF systems, the point of comparison is to Ivy Bridge. And it's certainly not even remotely close to being 4 times faster than Nehalem.
Say your old machine can do 60 fps at a given heat rate, but the new one can do 240 fps.
Haswell is not 4 times faster than Ivy Bridge. Also, most modern games struggle to get over 60fps - even on an older game like Crysis: Warhead, the Titan behemoth card can't break 60fps at 1080p max settings. If you're running a low end game at 240fps, then you're better off with an AMD Fusion chip to save on power consumption over an NVIDIA 670.
And that's ignoring that modern multithreaded game engines tend to decouple the render loop and gameplay loop so vsync doesn't necessarily cause the CPU to idle.
But for the sake of argument, let's assume I'm completely wrong on all points above. Let's do some rough math. 25% of the time running at load TDP and 75% at idle... My i5-3570k Ivy Bridge tends to idle around 20W (max TDP 77W), so that's averaging 0.25*77 + 0.75*20 for an average of 34.25W. Haswell has a higher TDP at load, i5-4670k rated around 88W. AnandTech have done power consumption benchmarks which indicates that the Haswell platform as a whole idles 10W lower overall, which includes power savings in the chipset and other motherboard aspects but let's call that a 10W CPU idle. Average power consumption would be 0.25*88 + 0.75*10 for an average of 29.5W. A savings of 5W due to Haswell in your scenario pales in comparison to the 170W NVIDIA 670 sitting in the corner, so no, even then Haswell doesn't change the thermal envelope appreciably such that these SFF platforms suddenly become viable. Besides, they still need to be built to cool the system under full load conditions anyway and that certainly hasn't changed.
