AMD releases list of compatible DirectX 12 graphics cards & APUs
AMD posted a thing or two on its blog about the DX12 API. The blog entry also lists a handy overview of what cards are actually DX12 compatible.
Now very little is new to the list, other then the fact that AMD is confirming DX12 compatibility with products based on the GPU/IGPs below. Presuming you’ve installed Windows 10 Technical Preview Build 10041 (or later) and obtained the latest driver from Windows Update, here’s the list of DirectX 12-ready AMD components.
- AMD Radeon R9 Series graphics
- AMD Radeon R7 Series graphics
- AMD Radeon R5 240 graphics
- AMD Radeon HD 8000 Series graphics for OEM systems (HD 8570 and up)
- AMD Radeon HD 8000M Series graphics for notebooks
- AMD Radeon HD 7000 Series graphics (HD 7730 and up)
- AMD Radeon HD 7000M Series graphics for notebooks (HD 7730M and up)
- AMD A4/A6/A8/A10-7000 Series APUs (codenamed “Kaveri”)
- AMD A6/A8/A10 PRO-7000 Series APUs (codenamed “Kaveri”)
- AMD E1/A4/A10 Micro-6000 Series APUs (codenamed “Mullins”)

Specifically a graphics API is hardly low-level when there is still significant level of abstraction that hides away specific hardware implementation details, even though memory/resource management has been reworked to have less abstraction and automatic memory management.
In highly abstracted object-oriented languages like Visual Basic .Net/C#, JavaScript/TypeScript, Python and Perl/PHP almost everything is an "object" - even basic variables which would be just a simple scalar type (integer, float, string, and boolean) in lower-level languages.
You do have a point, but your language analogy is a bit off.
There is a direct analogy since system-level APIs are closely tied to a particular programming language and the underlying hardware architecture.

I wouldn't include C++ as necessarily higher-level than C.
C++ features that are specific to object-oriented programming ("classes" (objects) with member functions/sctructures, inheritance/polymorphism of classes, operator overloads for custom object manipulation, and templates) do provide a higher level of abstraction comparing to simple pointer-based memory model of standard C.

C++ can be lower-level or higher-level. It's a flexible language.
Because the lower-level part of C++ that operates on scalar types is essentially C.
Also, low-level languages do provide abstraction. Assembly language falls into this category, there is not always a 1:1 correspondence between an assembly instruction and the underlying machine code instruction(s).
Any assembly code is still a low-level language because the level of abstraction is very minimal, even when there's no direct 1:1 mapping and there are several mnemonics/operands for a given machine code or different machine codes for a specific mnemonic/operand.

Wikipedia - Direct3D 12 feature levels
If we really have to go deeply technical, that slide from a Brazilian forum is not correct on several counts. First, none of GCN chips support rasterizer ordered views, conservative rasterization, or tiled resources tier 3 (ie. "volume tiled resources" with Texture3D support). GCN 1.1/1.2 (GCN2/GCN3 in AMD language) support tiled resourced tier 2 (with Texture2D support) - hence they are both at feature level 12_0. GCN 1.0 "only" supports tiled resources tier 1, hence feature level 11_1. Double precision floats are supported across the entire range. As for Nvidia, Kepler and Maxwell-1 do support resource binding tier 2, and do not support typed UAV load for additional texture formats - this leaves them at feature level 11_0. Maxwell-2 is currently the only card which supports feature level 12_1. It's not that it really matters much though.
All this has been verified against the latest SDK and preliminary WDDM 2.0 drivers. Conservative depth, SAD4 or dedicated atomic counter are not part of the current SDK, neither is "emulated" tier 3 for tiled resources.

gotta love the play on words both side use. There are no DX 12 HW cards there are cards that are compatible, and the compatible comes from mix of hw/software.
Atlest this how i always understood it since forever. We probably wont see fully HW DX12 cards till after Windows 10 is out

Not exactly.
~55% of currently installed graphics hardware on the desktop (as of Feb 2015 Steam survey) are fully compatible with Direct3D 12 (which amounts to 68% of D3D11.x cards out of total 78% share for all D3D11.x cards). This includes 100% of feature level 11_1 cards and ~50% of feature level 11_0 cards (specifically all 11_0 cards from Nvidia, but not Intel Ivy Bridge or AMD Evergreen/Terascale).
However a small share of these Direct3D12 compatible parts have minor optional features that qualify them for higher feature levels 12_0 and 12_1 (currently about 3-5% each out of all Direct3D 12 compliant GPUs on the desktop).
Now AMD explicitly specified mobile and APU parts as well.
