CPU Database

[bawsko]

There's a lot of missing generations right now sadly. Right now the goal is to catch up on Xeons, then mobile Core, then Atom and enterprise embedded SoCs.

Is there any chance you guys are going to have a way to list all CPUs at once or add a way to query the database with an API? Multiple people have requested it and nobody has said yes or no.

I don't handle the backend features in any way, which is why there hasn't been an answer. W1zzard has to implement those kinds of changes.

No plans for an API. We're spending thousands of dollars and lots of man-hours on this free project, so we need to make back some money from the ads.
If you really really want to scrape our data, there's nothing we can do except make it harder, so you rather continue using our database vs. effort and infrastructure to scrape

Thanks for addressing the question. Unfortunately, the database in its existing form is useless to people like me as I'm not going to manually query hundreds of computers to determine processor age. If you ever plan on making an API or selling the data in CSV for private use, please let me know.

I've noticed that the Tiger Lake H35 Processors have the wrong core counts, showing 6c/8t instead of 4c/8t. also why are the TDPs set to the configurable "down" one?

Good catch. Must have missed that when duplicating pages.

also why are the TDPs set to the configurable "down" one?

Whenever Intel or AMD does not provide a target TDP it defaults to the minimum guaranteed value so that the specs reflect a definitive baseline. For TL-H35 they only provide a range of 28-35W, not a definitive 35W. We assume that specs will be at that baseline of 28W unless configured appropriately by vendors. Helps avoid people checking their specs against our database and being confused as to why their chip is clocked much lower than presented.

I've found a quite weird CPU. It's a quad-core AMD FX-8800P.

https://www.amazon.com/A555DG-EHFX-Full-HD-FX-8800-Graphics-Windows/dp/B01D90P8ZO

Some sites say this laptop has AMD R5, R7, R8 or R9 graphics, but all of them are already documented here, the CPU isn't.

For what's worth, AMD does list it. It's a Carrizo CPU.

why not a performance comparison like in the gpu's?

 

[lexluthermiester]

Just went searching for the E5 V4 Xeon line-up to check the unlocked status of a few models and found nothing at all. Am I missing something or is the database missing the entire V4 series of CPU's?
Can't find the any of the models from E5-1603 V4 up to the E5-4669 V4. Can't seem to find any of the E3 V4 or E7 V4 models either. Nothing from the Broadwell DE, Broadwell EP or Broadwell EX seems to exist in the database.

This is "Twilight Zone" kind of weird.

Much of this is incomplete. Some Skylake derivative laptop CPU's are missing, for example.

It's on the way. Still catching up on fixes and the V3 lineup. Got Skylake Xeon W added only a couple weeks ago. If you could advise AMD and Intel to stop launching SKUs in batches of ~100, and secretly launching SKUs that we only hear about from Geekbench leaks, that'd be great.

Fair enough.

Sorry if this was already mentioned, but any plans to add a relative performance table like in the GPU database?

Not currently. Maybe if there's a consensus on what data set the algorithm will use to determine relative performance. TPU doesn't test as many CPUs like it does GPUs, and finding a simple performance variable that every chip across the ages fits nicely with in a graph is hard. Like, for example, pure ALU integer performance. We've seen time and again that slapping more ALUs into an execution block does not necessarily make a faster chip (Bulldozer, Itanium, PA-RISC, etc) but can help gain an edge in specific workloads if those workloads are coded and compiled to take advantage of that architecture. So how do we balance architectural improvement influences vs core count vs core clock vs fabric improvements into a relative performance chart? It's hard to select a metric that can easily be plugged in and get an output that reflects real life performance across the board.

How are CPUs added to this database? I can't seem to find Intel's Celeron N3000 series and above.

Hello guys. Is there an easy way to add to the database CPU comparison view for a few CPUs? Something along the lines motherboard vendors have on their websites - to choose up to three-four SKUs/boards/laptops and see all data categories vertically?

It's something I want to add, just no time. For now best best is to open two tabs and toggle between them

None of the Broadwell Xeons (E3, E5 and E7 v4) are unlocked and none of them are susceptible to any exploit which will increase their clock speed. The only unlocked Xeons on LGA 2011 v3 are the Haswell-E/EP variants of the E5-1600 v3 series, the other series (2600 series -EP, -EP 4S, -EX) are also locked. Retail stepping E5 v3 chips have an exploit that applies single-thread turbo bin to all cores by initializing the CPU without a microcode and then loading it on-the-fly. Some EFI plugins were written to reprogram the MSR in order to attempt to disable the AVX offset, but I have never gotten any to work on my E5-4669 v3.

Are you sure?

 

[Dr. Dro]

Are you sure?

Positive. Though, you can get a faster chip by opting to get something like a -1680 v4 or a -2687W v4 which should be plenty good. The i7-6850K has devalued quite a bit and should clock high, too.

Posting my quick reference (it's mostly accurate as far as I know):

LGA 771: Core 2 Extreme QX9775 only, all Xeon-branded processors are locked
LGA 1366: Core i7 Extreme Edition (i7-965, 975, 980X, 990X), plus Xeon W3570, W3580, W3680, W3690 are unlocked, all other models are locked, though BCLK overclocking is possible
LGA 2011: Core i7-3820 and Xeon E5-1620 are partially unlocked and have a maximum multiplier of 43x; Core i7-3930K/3960X, i7-4820K/4930K/4960X, E5-1600 and -1600 v2 families are unlocked, E5-2600 and -2600 v2 CPUs are locked
LGA 2011 v3: Core i7-branded parts, i7-5820K and i7-6800K are fully unlocked but restricted to 28 PCIe lanes, Xeon E5-1600 v3 series only: E5-2600 v3, -4600 v3, all v4 CPUs are locked - including -1600 v4
LGA 2066: all Xeon-branded processors are locked
LGA 3467: Xeon W-3175X only, all other processors are locked

1603, 1607 (V2), and 1620 V2 are exceptions and are not unlocked.

 

[Dr. Dro]

1603, 1607 (V2), and 1620 V2 are exceptions and are not unlocked.

Yeah, there are a few. I had a E5-1607 v4, I can also confirm that one is locked from first-hand experience, but seems all of the v4's are anyway. Its a big ol' mess. Generally if there's a i7-branded counterpart close by, there's a high chance of your Xeon CPU being unlocked. It still had access to all PCIe lanes, though, despite being from the same series of the 6800K (iirc the 6950X is SR2PA, 6800K is SR2PD, 1607 v4 is SR2PH). There's also a thread on STH forums that should be of some use:

Xeons with an open multiplier | ServeTheHome Forums

It's still all messy though, it'd be amazing if a CPU database could actually double-check and reverify all of this info scattered on forums and Discord over the years.
