SiSoftware Sandra Titanium (2018) SP4/a/c Update: Retpoline and hardware support

We are pleased to release SP4/a/c (version 28.69) update for Sandra Titanium (2018) with the following updates:

What is Retpoline?

It is a mitigation against ‘Spectre‘ 2 variant (BTI – Branch Target Injection) that affects just about all CPUs (not just Intel but AMD, ARM, etc.). While ‘Spectre’ does not have the same overall performance impact degradation as ‘Meltdown‘ (RDCL – Rogue Data Cache Load) it can have a sizeable impact on some processors and workloads. At this time no CPUs contain hardware mitigation for Spectre without performance impact.

Retpoline (Return Trampoline) is a faster way to mitigate against it without restricting branch speculation in kernel mode (using IBRS/IBPB) and has recently been added to Linux and now Windows version 1809 builds with KB4482887. Note that it still needs to be enabled in registry via the Mitigation Features Override flags as by default it is not enabled.

What CPUs can Retpoline be used on?

Unfortunately Retpoline is only safe to use on some CPUs: AMD CPUs (though does not engage on Ryzen, see below), Intel Broadwell or older (v5 and earlier) – thus not Skylake (v6 or later).

Windows speculation control settings reporting:

Intel Haswell (Core v4), Broadwell (v5) – Retpoline enabled, KATI enabled
Kernel Retpoline Speculation Control – Enabled

Kernel Address Table Import Optimisation – Enabled

(Note RDCL mitigations KVA, L1TF are also enabled as required)

Intel Skylake (Core v6), Kabylake (v7), Skylake/Kabylake-X (v6x) – no Retpoline, KATI can be enabled
Kernel Retpoline Speculation Control – no

Kernel Address Table Import Optimisation – no/yes (can be enabled)

(Note RDCL mitigations KVA, L1TF are enabled as required)

Intel Coffeelake-R (Core v8r), Whiskeylake/AmberLake (Core v8r), CometLake* – no Retpoline, KATI not enabled
Kernel Retpoline Speculation Control – no

Kernel Address Table Import Optimisation – Enabled

Note 2019/June: Latest microcode (AEh) with MDS vulnerability support cause Windows to report KVA/L1TF mitigations as required despite CPU claiming to not be vulnerable to RDCL.

Intel Atom Braswell (Atom v5), GeminiLake/ApolloLake (Atom v6) – no Retpoline but KATI enabled
Kernel Retpoline Speculation Control – no

Kernel Address Table Import Optimisation – Enabled

(Note RDCL mitigations KVA, L1TF are enabled as required)

AMD Ryzen (Threadripper) 1, 2 – no Retpoline, no KATI
Kernel Retpoline Speculation Control – no (should be usable?)

Kernel Address Table Import Optimisation – no (should be usable)

(Note CPU does not require RDCL mitigation thus no KVA, L1TF required)

From our somewhat limited testing above it seems that:

  • Intel Haswell/Broadwell (Core v4/v5) and perhaps earlier (Ivy Bridge/Sandy Bridge Core v3/v2) users are in luck, Retpoline is enabled and should improve performance; unfortunately RDCL (“Meltdown” mitigation) remains.
  • Intel Coffeelake-R (Core v8r refresh), Whiskylake ULV (v8r) users do benefit a bit more for their investment – while Retpoline is not enabled, KATI is enabled and should help. Not requiring KVA is the biggest gain of CFL-R. 2019/June: latest microcode (AEh) causes Windows to require KVA/L1TF thus negating any benefit CFL-R had over original CFL/KBL/SKL.
  • Intel Skylake (Core v6), Kabylake (v7) and Coffeelake (v8) are not able to benefit from Retpoline but KATI can work on some systems (driver dependent). However, on our Skylake ULV, Skylake-X test systems KATI could not be enabled. We are investigating further.
  • Intel Atom (v4/v5+) users should be able to use Retpoline but it seems it cannot be enabled currently. KATI is enabled.
  • AMD Ryzen (Threadripper) 1/2 users should also be able to use Retpoline but it seems it cannot be enabled currently. While RDCL is not required, mitigations for Spectre v2 are required and should be enabled. We are investigating further.

SiSoftware Sandra Titanium (2018) SP3a/b Update: Pushing the Limits

Note: This article originally announced SP3a (28.45); it has since been updated to SP3b (28.49).

We are pleased to announce SP3b (version 28.49 for Sandra Titanium (2018) with updated hardware and software support:

Sandra Titanium (2018) Press Release

Sandra has always pushed the limits of hardware, optimising the workload based on the capablities of the device (compute performance, memory/storage size, etc.) ensuring that both low-end devices and high-end devices are used to their best of their capability.

This new version pushes the workload even higher with better scaling across all GPGPU benchmarks allowing low-end devices to work (e.g. integrated graphics, emulation on CPU) and high-end professional GPGPU accelerators with very fast, very large memory.

GPGPU Benchmarks

  • All Benchmarks: increased workload size on all benchmarks to up to maximum device capacity.
  • FP16/half optimisations for AMD Vega and Radeon VII (vectorisation)*
  • FP16/half optimisations for nVidia Volta/Turing (half2) [CUDA 10]
  • Workgroup and workload optimisations for AMD Vega and Radeon VII*
  • Updated DirectX and OpenGL compute to match CUDA and OpenCL
  • Resolved “out of memory” issues on low-end hardware**
  • Resolved long running time of CPU test-paths (that the GPGPU test paths are checked against) by enabling SIMD implementation (FFT/GEMM)**

Note: At this time we have not personally tested Radeon VII to confirm improvements.

Note2: Applies to SP3b update.

Hardware Support

  • Intel Core v8r Mobile WhiskyLake (WHL), AmberLake (AML) support (based on public information)

Ranker Hardware Results

Note: FP64 rate on Radeon VII is 1/4 not 1/8 as stated in some places. FP16 rate is 2x with vectorisation, 1x with scalar.

SiSoftware Sandra Titanium (2018) SP3 Update

We are pleased to announce SP3 (version 28.40 for Sandra Titanium (2018) with updated hardware and software support:

Sandra Titanium (2018) Press Release

GPGPU Benchmarks:

  • Enable FP16/half support in CUDA benchmarks*
  • Enable low-precision FP32 shader support in DirectX Compute benchmarks
  • Enable Tensor support for CUDA/GEMM/FP16

Note: FP16 is already supported by the OpenCL and DirectX compute benchmarks.

GPGPU Processing, Video Shader Benchmarks:

  • FP16/half-precision performance* (if supported) is included in the aggregate scores. This better reflects the performance of new GPGPUs that natively support FP16/half processing.
  • Tensors code-path used by default where applicable.

Note: FP16 is supported by all benchmarks: DirectX, OpenGL, OpenCL and now CUDA.
